Error 809 when connecting to the Internet in Windows. Errors when creating a VPN connection. "Encryption settings are incorrectly configured"

Error 809 causes a lot of trouble for users. There are many reasons for its occurrence. However, there is no need to worry.

The problem can be fixed fairly quickly.

The main thing that is required is to strictly follow our rules.

There are several reasons why VPN error number 809 occurs:

Reconnection

This VPN malfunction occurs for users who have entered into an agreement with the Beeline provider or use the L2TP protocol using IpSec. The most basic thing to do when malfunctions are detected is to check. It is necessary to analyze all connected cables and network card, and then reconnect.

In most cases, this is not the problem, so next you should test your firewall and antivirus.

Firewall or antivirus

By default, the firewall blocks many VPN connections to certain ports. To resolve the error, you need to perform several manipulations:

After these manipulations, reconnect. If we are unable to connect, move on.

You need to scan your computer or laptop for viruses. This is probably why the VPN error appears. Once viruses are detected, it is recommended to cure or remove them.
After that, try to connect again.

Registry changes

In many cases, making changes to the registry will help troubleshoot problems. To activate the program, click “Start”. Next, enter regedit in the search bar.
The sequence of actions to resolve the VPN error is as follows:

It is worth noting that some MicroTik router models are used at home or in small offices. Therefore, the question of changes in the registry to eliminate this error regarding this router is relevant.

To start the program, press the Win + R keys. Then do the following manipulations:

After the above steps, the connection should be restored, which will resolve the error.

Conclusion

This type of VPN problem causes a lot of trouble for users. However this is quite simple mistake, which can be eliminated very simply and quickly. The main thing is to follow all these recommendations and there will be no problems.

Manually editing the Windows registry to remove invalid Error 809 keys is not recommended unless you are a PC service professional. Mistakes made when editing the registry can render your PC inoperable and cause irreparable damage to your operating system. In fact, even one comma placed in the wrong place can prevent your computer from booting!

Because of this risk, we highly recommend using a trusted registry cleaner such as WinThruster [Download] (developed by Microsoft Gold Certified Partner) to scan and repair any Error 809-related issues. Using Registry Cleaner [Download] you will be able to automate the process of finding corrupted registry entries, missing file references (such as those causing the %%error_name% error), and broken links within the registry. Before each scan, a backup copy is automatically created, allowing you to undo any changes with one click and protecting you from possible damage to your computer. The best part is that fixing registry errors [Download] can dramatically improve system speed and performance.

Warning: If you are not experienced user PC, we DO NOT recommend manually editing the Windows registry. Using Registry Editor incorrectly can cause serious problems and require Windows reinstallation. We do not guarantee that problems resulting from incorrect use of Registry Editor can be corrected. You use Registry Editor at your own risk.

Before manually restoring Windows registry, you need to create backup copy by exporting the part of the registry associated with Error 809 (for example, Windows 8.1):

1. Click on the button Begin.
2. Enter " command" V search bar... DON'T CLICK YET ENTER!
3. While holding down the keys CTRL-Shift on your keyboard, press ENTER.
4. A dialog box for access will be displayed.
5. Click Yes.
6. The black box opens with a blinking cursor.
7. Enter " regedit" and press ENTER.
8. In the Registry Editor, select the Error 809-related key (for example, Windows 8.1) that you want to back up.
9. On the menu File select Export.
10. On the list Save to select the folder where you want to save the backup Windows key 8.1.
11. In field File name Enter a name for the backup file, for example "Windows 8.1 backup".
12. Make sure the field Export range value selected Selected branch.
13. Click Save.
14. The file will be saved with extension .reg.
15. You now have a backup of your Windows 8.1-related registry entry.

The following steps for manually editing the registry will not be described in this article, as they are likely to damage your system. If you would like more information about editing the registry manually, please check out the links below.

First of all, it should be noted that installation problems VPN connections does not occur on computers with a working system installed from official disks operating system Windows and in the absence of third-party protection tools (anti-virus software, firewalls, etc.)

Installed antivirus software and in particular, firewalls can block the establishment of a VPN connection, causing, for example, errors 789 and 792. In this case, it is necessary to allow UDP ports 500 and 4500 in the security settings for communication with the VPN concentrator.

If the VPN connection is not established

In addition, problems with establishing a VPN connection does not occur on computers directly connected to the Internet with an IP address routable on the Internet (and not an address from the private address space: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/24). Otherwise, your administrator local network(or the ISP if the private IP address is obtained from one) must configure address translation (NAT/PAT).

Please note that connecting your computer to the Internet means that you have access to data exchange at the network (IP) level with any other computer on the Internet. Protocols used for setting up a VPN connection(IPsec protocols) have equal rights on the Internet with any other protocols that work on top of the protocol network layer(IP) - for example, the HTTP protocol for browsing web pages or the SMTP protocol for sending Email. If your Internet provider allows web browsing but blocks the establishment of a VPN connection, this is artificially limiting your access to the Internet.

Make sure the following are running Windows services XP
(“Start” - “Control Panel” - “Administration” - “Services”):
"Telephony";
“Remote access auto connection manager”;
"Remote Access Connection Manager".

Below are some of the most common errors encountered when establishing a VPN connection and recommendations for eliminating them.

Setting up a VPN connection in Windows XP

This section describes how to set up a VPN in Windows XP. If you are interested in how to set up a VPN in Windows Vista or Windows 7, then look at here

You can also familiarize yourself with setting up a VPN for Linux, and instructions for configure routers here.

New Connection Wizard

Press the button "Start" in the lower left corner of the desktop, in the main menu of the system that appears, select the item "Control Panel", if your control panel looks like “XP Style” and you cannot find the icon "Network connections", go to the classic panel view by selecting the appropriate item on the left side of the window:

or select "Network connections" directly from the main menu "Start":

If you are seeing a Classic View window, look for the icon "Network connections" and open it, in the window that opens, find and run "New Connection Wizard":

In the first window, just click the button "Further":

In the second, select “Connect to the network at your workplace” and press the button "Further":

In the third select "Connect to a virtual private network" and press the button "Further":

In the fourth, in the free field, enter the name for your connection, for example, "Internet VPN" and press the button "Further":

On some computers where there are other connections, between step 4 and step 5 an additional window appears asking you to dial a number to connect. In this case, you need to stop dialing the number and go to step 5.

In the fifth window, enter the IP address of the default access gateway nas.iksnet(or nas3.iksnet for some subscribers) and click the “Next” button (note that there should not be any spaces or other invisible characters before or after the server name):

In the sixth, for ease of use, check the box “Add a connection shortcut to the desktop” and press the button "Ready":

Connection properties

After this, the connection window will immediately open; at the bottom of the window, find the button "Properties" and click on it:

Or click the button "Cancel" and having selected the connection, right-click on it and select "Properties":

In the window that opens, select the tab "Options", uncheck the item "Enable login domain in Windows":

In the "Security" tab, remove tick the item "Data encryption required" and click on the “OK” button:

On the tab "Options" you can check the box next to it “Call back when disconnected”, then, in case of an unexpected break, the connection will be restored on its own:

Let's connect:

Now in the field "User" You must enter your contract number ( for those subscribers who have a three-digit contract number, add “0” in front! For example, an agreement 111 typed as 0111 .), and in the field "Password", your access password to view statistics and mail from the contract. Please note that there should not be any extra spaces after the contract number in the “User” field.

After a successful connection, for ease of use, on the tab "Options" you can uncheck the box “Request name, password, certificate, etc.”, after this you will no longer be prompted for your username and password.

Saving your password

Attention: It is not recommended to save a password in the system, because the saved login and password can be stolen spyware or your computer may be used to access the Internet while you are away.

Please note that access to the Internet is controlled by name and password, so take this moment more seriously. Do not disclose this data to strangers. If your password is too simple and short, in order to increase security, we suggest changing it. You can do this yourself, from your workplace, using the client part new system calculations, available at the link: Statistics. There you can change the password separately for entering the statistics page and separately for accessing the Internet. We hope that you can still find a lot of new, interesting and useful things there!

Note

When the VPN connection is disabled, you can still freely use the resources of the local network as before; a VPN connection is only needed to access the external network. If you have turned it off, be sure to turn it on to create a VPN connection. "LAN connection" otherwise the VPN connection will not be established.

Errors

Most often the system issues following errors:

Error 619 or 734

• Occurs if you forgot to uncheck the “Required data encryption"In the connection properties, the "Security" tab.

Error 629

This error occurs if your login and password are already connected (remember if you didn’t let someone you know use your Internet), if not, then this connection is not broken on the server. To do this, wait 10 minutes, and try to connect again after this time... If nothing helps on the 3rd attempt, then I advise you to contact support.

Error 650

"The remote access server is not responding":

• The Internet access server is unavailable. Check if "Local Area Connection" is enabled, if the network card is working, if the network cable, whether a specific IP address is set in the IP connection settings.

Error 651 or 800

Your modem (or other device) has reported an error" or "No connection to VPN connection server"

• These errors may occur if you deleted or disabled the previous “Local Area Connection” connection.
• Or if you specified in step 5 wrong address. Check it, make sure the numbers are separated by periods and not commas.
• Firewall blocks outgoing requests for VPN connections.
• For some reason the request does not reach the server, i.e. Perhaps the gateway of your segment does not allow the request due to load or failure.
• The server sends a response stating that it is impossible to connect because... There are currently a large number of simultaneous connection attempts.

Possible fixes

• Check whether the local network is working at this point in time.
• Check the passage of the signal using the ping command to your gateway, and then to your authorization server.
• Correct a pair of keys in the registry or reinstall Windows

Error 678

"No response received"

• If it doesn’t help, try re-creating the VPN connection again (pay attention to the connection type, it should be PPTP, not PPPoE or L2TP).
• This error can also occur when negative balance your personal account.

Error 679

• This error Occurs when the network adapter is disabled. You need to enable the network adapter by going to “START->Control Panel->System->Device Manager->Hardware”.

Error 691 or 718

"Wrong login or password"

• Check whether the login (contract number) is entered correctly. It must be 4 digits (three-digit contract numbers must be padded with a leading zero). Try typing your username and password again. When typing, make sure that the correct keyboard layout (typing language) is turned on and that the Caps Lock indicator is on.
• Or if at the moment
• If the operating system does not prompt you to enter a username and password when connecting, then you need to do the following: Open the “Control Panel”, select “Network Connections”, right-click on your VPN connection and select “Properties” from the menu. The properties of the VPN connection will open. Now you need to go to the “Settings” tab and check the box next to “Request name, password, certificate, etc.” After this, confirm the changes by clicking the "OK" button. The next time you connect, you will be prompted for your username and password.

Error 711

This error occurs if a required service is not running on the computer. In this case, it is impossible to connect to the network, and in some cases, it is impossible to install network adapters. This issue may occur if some or all of the following services are not running.

• Plug and Play device support
• Dispatcher automatic connections remote access
• Remote Access Connection Manager
• Telephony

To resolve this error, follow these steps for each of the services listed above.

1. Open Administrative Tools by clicking Start, Control Panel, System and Maintenance, and Administrative Tools.‍ Administrator permission is required Enter your administrator password or confirm your password if prompted.
2. Double-click Services. Administrator permission required Enter the administrator password or confirm the password if prompted.
3. Right-click one of the services above and then click Properties.
4. On the General tab, in Startup Type, select Manual.
5. Click Apply and then click Run.

Error 720

"Can't connect to remote computer."

This error occurs when the network protocol stack in Windows is damaged. You can check the integrity of the stack using the netdiag utility.

• Enter the command

• Netdiag will display test results for a number of network components, including Winsock. For more information about this check, run the netdiag command as follows:

• If Netdiag reports an error, you must restore the Winsock2 registry key.
• The simplest and quick way solutions:

• After this, we restart the computer and set up a local network connection, since executing this command leads to overwriting the registry settings that are used by the TCP/IP protocol stack, which is equivalent to deleting it and reinstallation. If necessary, recreate the VPN connection.
• If this does not help, then you can completely reinstall the TCP/IP stack like this:

1. Delete the registry key with REG DELETE HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
2. Delete the registry key with REG DELETE HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
3. Restart your computer
4. Open the %winroot%\inf folder
5. Find the file nettcpip.inf in it, make a backup copy of it and then open it in text editor(for example Notepad).
6. Find the lines in it:

1. Correct them to:

1. Save changes to nettcpip.inf file
2. Open Network Connections and right-click on the property we need network connection select Install->Protocol->Add. Next, select "have disk" and specify the path %winroot%\inf (usually this folder is hidden!)
3. Select TCP/IP from the list. After this, you will again be taken to the network connection properties window, but for TCP/IP the Uninstall button will now be active.
4. Select the TCP/IP protocol from the This connection uses the following items list and click the Uninstall button.
5. Restart your computer
6. Install the TCP/IP protocol similar to steps 2-5.

• If all of the above does not work, then look at the instructions at

Error 733

• Occurs if you forgot to uncheck all protocols except Internet Protocol And QoS.

Error 734

• Most likely you have a virus WIN32.Sality.

Error 735

• "The requested address was rejected by the server": Occurs if you entered IP address in "TCP/IP Properties"(it should be obtained automatically).

Errors 741 - 743

"Encryption settings are incorrectly configured"

• Go to the VPN connection settings, and in the "Security" tab, disable the "data encryption" item.

Error 764

"Smart card readers are not installed"

• This error occurs if you have configured your VPN connection incorrectly. Try removing it and setting it up again using these instructions.

Error 769

"The specified destination is unreachable"

• The error occurs due to a disabled local network connection or a missing physical link. It is recommended to check the LAN status (must be enabled) and physical connection to the network (the network cable must be connected).
• Sometimes it occurs if the router for some reason did not provide the correct IP address via DHCP

Error 781

"The encoding attempt failed because no valid certificate was found."

• Causes: The VPN client is trying to use the L2TP/IPSec protocol to connect.
• Tip: Go to VPN connection settings-Properties->Network->VPN Type and select PPTP VPN

Error 789

"Invalid VPN connection type selected"

• Go to the VPN connection settings and on the "Network" tab, from the "VPN Type" list, select "Automatic" or "PPTP". Try connecting again.
• This error also occurs if you made a mistake when entering the IP address and enter commas instead of periods to separate octets.

Error 807

If you are using the "Automatic" VPN connection type, try changing it to "PPTP". In the properties of the network card you need to set Receive-Side Scaling State - disable and Receive Window Auto-Tuning Level - disable. It is also possible that the connection to the access server is blocked by a firewall. You can also recreate the VPN connection according to the instructions; if the problem is not solved, remove the KB958869 system update, or restore the system to an earlier state.

Error 809

Occurs when:

1 Using L2TP VPN connection type in Windows Vista and Windows 7 due to the connection being blocked by the Windows firewall. Solution: Change the VPN connection type to PPPtP. Enable the firewall rule "Routing and Remote Access (PPPtP)"

2 Blocked by your installed firewall or antivirus with firewall function Solution: Correctly configure your firewall.

Error 1717

"Unknown interface"

• Try restarting your computer
• If it doesn’t help, then run it from the command line (check integrity system files)

In this case, the user will not be prompted to re-enter the login and password. What to do in this case.

The connection shortcut on the desktop in Windows Vista and 7 can be made as follows: Open the “Network and Sharing Center”, in the left column click the link “Change adapter settings”, in the window that opens you need to find your “VPN connection” (the name may be different, depending on how you specified the "Destination Name" during the setup process). Right-click on the connection and select “create shortcut”. By default, you will be asked to locate this shortcut on the desktop. Click "Yes".

Errors

Error 609

This method of solving the problem does not always work.

1. Launch Command Prompt (CMD) with Administrator rights
2. Enter the following commands (removing miniport drivers):

1. Now the next two (installing miniport drivers):

Error 619

"Port disabled"

Possible causes and solutions:

1. Operating system problems. In this case, we recommend contacting specialists.
2. The firewall is enabled. In this case, we recommend turning off the firewall.

Error 651

“Your modem (or other device) reported an error.”

Possible causes and solutions (in order of execution):

1. Operating system crash. In this case, we recommend restarting your computer.
2. The network card drivers are broken. We recommend reinstalling the drivers and reconfiguring the network.
3. Problems with the OS. We recommend reinstalling the operating system.
4. The network card is faulty. We recommend replacing the network card.

Error 678

"No response"

Often occurs when the MAC-IP binding is broken. In this case, the VPN servers and gateway are not pinged. In this case, it is recommended to call us and reset the MAC-IP binding.

The error may appear if you try to connect to a server that does not support the PPTP VPN protocol. We recommend reconfiguring the VPN connection using the auto-configurator or checking the settings manually.

Error 691 (Vista/7)

"Access is denied because this username and password are not allowed on this domain."

Appears in the following cases:

1. Invalid login/password entered. Completely clear the login/password entry window and enter them again. The login must be 4-digit (three-digit contract numbers must be padded with a leading zero). When typing, make sure that the correct keyboard layout (typing language) is turned on and that the Caps Lock indicator is on.
2. The VPN session ended incorrectly (connection failure, abnormal computer shutdown). In this case, you need to wait a few minutes.
3. Or if at the moment a connection has already been created with your username and password. (If you have more than one computer connected).
4. Quite often it happens that Windows “forgets” the entered login and password and then they must be entered again, having first been erased from the input fields.

• If the operating system does not prompt you to enter a user name and password when connecting, then you need to do the following: Open the “Control Panel”, select “Network and Sharing Center”, in the left column click on the “Change adapter settings” link, right-click Click on your VPN connection and select “Properties” from the menu. The properties of the VPN connection will open. Now you need to go to the “Settings” tab and check the box next to “Request name, password, certificate, etc.” After this, confirm the changes by clicking the "OK" button.

Error 814

"Base Ethernet connection not found"

• Error caused by unavailability network adapter, used for this connection.

Error 868

"DNS name not resolved"

• This error only occurs in Windows 7. The essence of the problem is that in some “builds” given Windows The DNS client is unstable.
• Solution:
  • Check that the DNS server addresses in the local network connection are obtained automatically (at the moment 10.0.1.5 and 192.168.2.1 should be issued)
  • Disable the IPv6 protocol (or better yet, everything except IPv4) in the local network connection properties
  • Set the access server address instead nas.iksnet in the form of an IP address (You need to select one of the server addresses. They can be checked with the command ping nas.iksnet, at the moment these are 10.0.1.13 and 10.0.1.14)
  • In some cases, resetting directories helps: enter the commands in the command line

Setting up a VPN on Linux

Debian

First install the required package:

$ apt-get install pptp-linux

Then edit the file describing the network interfaces. Here's an example:

$ cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 ppp9 iface eth0 inet dhcp iface ppp9 inet ppp provider iksnet pre-up ip link set eth0 up

Then edit the file describing your VPN connection. It should be something like this:

$ cat /etc/ppp/peers/iksnet unit 9 lock noauth nobsdcomp nodeflate #mtu 1300 persist maxfail 3 lcp-echo-interval 60 lcp-echo-failure 4 pty "pptp nas.iksnet --nolaunchpppd --loglevel 0" name # Your contract number remotename iksnet ipparam iksnet defaultroute replacedefaultroute usepeerdns #nodebug kdebug 0

After that, enter your credentials = contract number, = VPN password into the file (note the quotes for the password):

$ cat /etc/ppp/chap-secrets * " " *

And after that you can manually connect the VPN:

$ifupppp9

And turn it off:

$ifdownppp9

The connection can be checked using the command:

$ ifconfig ppp9 ppp9 Link encap:Point-to-Point Protocol inet addr:89.113.252.65 P-t-P:10.0.1.11 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1450 Metric:1 RX packets:40 errors:0 dropped:0 overruns:0 frame:0 TX packets:418 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:7750 (7.5 KiB) TX bytes:1189 (1.1 KiB)

We wish you pleasant work and sincerely hope for constructive cooperation in order to improve the quality of services. You can leave your questions and suggestions in the “HelpDesk” section of the new payment system - these questions will be visible only to our technical service, or by calling 2-55-24.

If at starting a VPN connection an error occurs, you need to remember its three-digit code. Errors with code 6ХХ (errors associated with incorrectly entering a password, name or choice of communication protocol type and indicate that the network is working, but it is necessary to check the entered data), 7ХХ (errors associated with incorrect and indicating that the network is working , but you need to check the settings) or 8ХХ (errors related to problems in network settings or lack of connection to the network.

Installed antivirus software and especially firewalls may block VPN connection establishment, causing, for example, errors 789 and 792. In this case, it is necessary to allow UDP ports 500 and 4500 in the security settings for data exchange with the VPN concentrator.

If the VPN connection cannot be established and displays an error

In addition, problems with establishing a VPN connection does not occur on computers directly connected to the Internet receiving an IP address forwarded on the Internet (and not an address from the private address space: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/24). Otherwise, Your local network administrator (or ISP if you obtained the private IP address from them) must configure address translation (NAT/PAT).

Please note that connecting your computer to the Internet means that you have access to data exchange at the network (IP) level with any other computer on the Internet. Protocols used for setting up a VPN connection(IPsec protocols) are equal on the Internet to any other protocol that runs on top of the network layer protocol (IP) - for example, HTTP for web browsing or SMTP for sending email. If your Internet service provider allows web browsing, but blocks the establishment of a VPN connection, this is an artificial restriction of your access to the Internet.

Make sure that the following Windows XP services are running (Start - Control Panel - Administrative Tools - Services):
— “Telephony”;
— “Remote access auto connection manager”;
— “Remote access connection manager.”

To enable them, run the following commands on the command line:

sc config RasAuto start= demand
sc config RasMan start= demand
sc config TapiSrv start= demand
