In this article, we have discussed a few vital causes and solutions to rectify VPN error 809 in USA. Let’s see what solutions we have gathered for you.

Fix the VPN Error 809 In USA on Windows

Here are several solutions for Windows users experiencing VPN error 809 in USA:

1. Enable the Ports on Your Firewall/Router

In most cases, the VPN error 809 in USA windows 11 is brought on by a firewall or router that is restricting access to the PPTP port (TCP 1723) or the IKEv2 port, or the port L2TP. It is possible that you may experience this problem because your VPN utilizes the IKEv2 protocol.

The solution is not as difficult as you might think! To open the ports, you simply need to enable them on your firewall or router.

2. Add Value to the Windows Registry

If your MX is located there behind the NAT and you are attempting to make a VPN connection, you must add the “AssumeUDPEncapsulationContextOnSendRule” DWORD parameter to the Windows registry.

This enables Windows to build an encrypted channel when both the VPN server and the client system are located behind NAT devices. Here’s how:

  • Log into Windows with admin privileges.
  • Enter “Run” in the search field and then select the application.


  • Enter “regedit” and press ‘OK.’


  • Now in the open Window, locate the following path: PolicyAgent is located under HKEY LOCAL MACHINE >> SYSTEM >> CurrentControlSet > Services.


  • Right-click the route and then create a new ‘DWORD (32-bit) Value‘.


  • Replace the current value with “AssumeUDPEncapsulationContextOnSendRule.
  • Change the new entry’s Value Data from “0” to “2” and then click “OK.”


  • Restart the device and verify the connection. This is an ideal approach when a client computer is located behind NAT devices.

3. Disable Xbox Live Networking services

A Windows 10 application may prohibit connectivity to the L2TP/IPsec VPN. To remedy this issue and avoid encountering error 809 in USA , you can do the following:

  • Enter “services” in the search box, then click “Services.
  • Double-click “Xbox Live Networking Services” when you find it.
  • In the ‘startup type‘ drop-down option, select “Disabled.
  • Click “Apply” and then click “OK.”


Confirm that your VPN connection is active and working.

4. Enable IKEv2 Fragmentation

IKE fragmentation can cause VPN error 809 in USA windows 10 while utilizing the IKEv2 which is the best VPN protocol in USA other than L2TP or PPTP. However, allow me to provide a concise explanation. Windows VPN error in USA is a common issue when using a VPN on the Windows platform.

During the client-to-server IKEv2 connection, the data packet may surpass the IP Maximum Transmission Unit. This leads to the fragmentation of the packets. Due to fragmentation, intermediate devices such as routers, NAT devices, and firewalls will occasionally block IP fragments.

The VPN connection will therefore not be formed. Even though it seems hard, the solution to this problem is simple! Updating your Windows 10 devices to the newest version available. Windows 10 1803 introduces IKEv2 fragmentation, which is activated by default.

Kudos!  Your VPN should now function without any errors. For more information, you can read our comparison of L2TP Vs PPTP in USA. You can also strengthen your understanding by reading more about Windows VPN errors including Error 628, Error 619, Error 720, and Error 868 in USA.
