It happens that PC owners who are trying to create a VPN connection to the Internet face all sorts of problems, among which error 809 is common. This leads a person to confusion, especially if he absolutely does not understand the causes of errors and the existing ways to eliminate them.
We will analyze the main causes of error 809 and the ways to solve it in this article.

Factors contributing to the manifestation of problems
There are several reasons why a 809 VPN error may occur, preventing the creation of access to the global network. If these causes are identified correctly, it will be much easier to eliminate the problem, since there are recommendations that allow you to make the required changes to the settings quite simply and ensure a VPN connection to the network.
Causes of the problem
Error 809 occurs when someone is trying to create network access using a VPN connection, which is a type of virtual private network.
The firewall, a mandatory component of the operating system, blocks attempts to make such a connection. In addition to the firewall, any device connected to the computer and participating in providing network access can block the network connection. One of the devices blocking access to the network can be a router, NAT.
An obvious cause of such a problem may be an incomplete installation of the OS, or in some cases an already installed system, but accompanied by some problems.
Sometimes they install software downloaded from unverified sources, as a result of which automatic changes are made to the system registry during installation, causing problems related to network access.
Discord in the system can be introduced by malicious software, as well as viruses that can not only damage, but also delete significant system files, without which it is impossible to provide access to the Internet.
Finding and eradicating the problem will avoid similar problems in the future.
Ways to eradicate errors
Having identified a probable problem, the user must make efforts to eliminate it. If you can’t fix problems on your own after reading the instructions, you should seek help from specialists who will quickly identify and eliminate errors without difficulty.
How to fix the problem yourself
Since missing registry settings are considered the most likely cause of an error during a VPN connection, it is very important to manually make all important changes.
Initially, you should find the registry branch in which important additions should be made.
To enter the registry and enter system additions into it, you should click “Start”, then enter regedit in the search bar.
If Windows XP is installed on the PC, the owner of the equipment must find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesIPSec. When Windows 7 or Vista is installed, the branch will look different: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesPolicyAgent.
Now, to make changes, select the required registry by clicking on it with the mouse, then in the “Edit” menu, select the “Create” submenu. From the proposed options, you must select DWORD.
An available line will open on the screen in which you need to make the required changes. The user must enter AssumeUDPEncapsulationContextOnSendRule into it, and then confirm the changes made.
After making additions to the system registry, the user must select it using the mouse and select the “Edit” option. In the field that appears, you can enter 0, 1 or 2, depending on the designated goals.
The value “0” is most often set by default and indicates that a network connection is not provided when using NAT devices.
The value “1” allows you to connect to the server using NAT devices.
The value “2” contributes to the successful configuration of the operating system in security mode, ensuring that the PC connects to the VPN-based server using NAT devices.
Of course, most often resort to the introduction of the value “2”. In order for all additions and changes to take effect, it is very important to restart the electronic computer.
When a VPN connection problem occurs due to viruses, it is important to update your antivirus application and run a full scan. It also does not hurt to clean the operating system by deleting all temporary files.
Installing updates, drivers can also help solve the problem, accompanied by the inscription “error 809”. If the cause of the problem is software that was installed incorrectly or came into conflict with other software, the System Restore function successfully helps, which allows you to roll back the system a few days ago, when there were no problems with the VPN connection.
And only in some cases it is necessary to reinstall the system, giving preference to a full boot of Windows.
So, system errors warn that some important additions are missing or incapacitated. In order to return all parameters to working capacity and provide access to the World Wide Web, efforts should be made, increased attention should be paid, and all recommended actions should be followed in sequence. Efforts will be well spent, since the contact of the computer with the server will be ensured.
