VPN Error 806 – What Does It Mean?

VPN Error 806 is generally caused by an incomplete connection.

3) Antivirus

To begin with, antivirus apps and software are often used in computers to keep the systems safe from security threats. Keep in mind that VPN error 806 can occur through an antivirus program. This is because there are various third-party utilities associated with the app, and switching them off will resolve the said error. If you don’t know how to switch off these third-party utilities, check the steps mentioned below;

  • Open the antivirus software and tap on the system tray
  • Tap on the disable option
  • The third-party utilities will be disabled and error might go away

4) VPN Service

What VPN service you are using can also impact the number of errors you get on the system. That being said, VPN error 806 can be caused by using an unreliable VPN Service. For the most part, the error occurs when you are using VPN connections that need manual configurations.

For this reason, you should opt for a reliable and commercial VPN because it offers secure anonymity without causing errors. In addition, some people set up the acceptance of incoming VPN connections (through port forwarding) and it tends to resolve VPN error 806.

5) Exception To Firewall

This is another solution for resolving VPN error 806. Adding this exception to the firewall can resolve the error 806, so let’s see how you can add an exception into the firewall, including the following;

  • Open the firewall and network protection from the control panel of your computer
  • Choose the “allow app through firewall”
  • Tap on the “change settings” and scroll down to the VPN app
  • When you find the VPN app, tick it to the private category, and you are done


The solution is all about allowing PPTP to move through the router. For this purpose, you have to check the admin page of the router and scroll down to PPTP passthrough settings. Now, enable the PPTP for outgoing as well as incoming settings to ensure the VPN traffic isn’t blocked. As a result, error 806 should be fixed. For the same reason, you should always opt for a router that comes with a built-in VPN feature.
