Setting up a VPN on your Windows computer can be a necessity these days. That’s why getting VPN errors is so frustrating. Some users have reported that they have encountered a VPN 806 error when trying to connect to a VPN. In this article, we are going to provide an overview of methods to fix the VPN 806 error. If you see this error, the VPN is not working, and this is the message you get in the command line window:
“There is a connection between your computer and the VPN server, but the VPN connection cannot be established. The error code is 806. The most common reason for this error is that at least one Internet device (such as a firewall or router) between your computer and the VPN server is not configured to allow GRE (Generic Routing Encapsulation) protocol packets. If the problem persists, contact your network administrator or ISP. “
How to fix the VPN connection error in Windows 10? We have several solutions worth trying. One of them is sure to help you.
There are several ways to fix the GRE port error code for VPN, including 806. However, the settings may vary slightly depending on the Windows operating system your computer is running on.
Open TCP port 1723
Type “firewall” in the search box and open the Windows Defender firewall in high security mode. Click incoming rules on the left side of the screen. Click Action> New Rule> Port> Next> TCP. Enter 1723> Next> Allow Connection> Next in the Specific Local Ports box. Make sure the 3 checkboxes on the screen are checked and click Next, then Finish.
Open Protocol 47 (GRE).
To do this, go back to Rules for Inbound Connections and select New Rule and Customizable. Then select Protocol and Ports on the left side of the window to open the options. From the Protocol Type drop-down menu, select GRE and click Done.
Add the VPN application to your antivirus program’s whitelist
If you don’t have third-party antivirus, Windows Defender is responsible for your firewall settings.
So if you’ve already added an exception for your VPN app using Windows Firewall, you don’t need to go through this step again.
Otherwise, run your anti-malware solution and be sure to add your VPN app to the whitelist field. This will prevent your VPN from being blocked by antivirus.
Add an exception to the firewall
- Go to Firewall and Network Protection
- Click Allow an application through the firewall.
- Click on Change settings (administrator rights required).
- Find your VPN application in this list and check the “Private” and “Public” boxes.
If you can’t find your VPN app here, click “Allow another app” to find and add it.
If your firewall didn’t whitelist your VPN when you created the secure tunnel, you may see an 806 VPN error in Windows 10.
Use a reliable VPN service.
Sometimes the 806 GRE blocked VPN error occurs when you manually set up a VPN connection. In this case, you’ll need the help of reliable VPN software to get out of this mess.
