A connection between your computer and the VPN server has been established but the VPN connection cannot be completed.

Use a reliable VPN service
If you manually configured a VPN connection on Windows 10, you might occasionally stumbled upon errors like 806.
To avoid this issue on the long term, we suggest opting for a commercial, reliable VPN service such as Private Internet Access. It sets up the secure tunnel automatically whenever you connect to a VPN server.
You can even set up your computer to accept incoming VPN connections by requesting port forwarding in PIA, without having to change any router settings.
More about PIA:
- OpenVPN, WireGuard, PPTP, and L2TP support
- 10 simultaneous connections
- 24/7 live chat support
- 30-day money-back guarantee (no free trial)
Private Internet Access
Use PIA to set up a secure tunnel on your Windows 10 PC without encountering errors like 806.
Add an exception to the firewall
- Go to Firewall & network protection
- Click Allow an app through firewall
- Click Change settings (you need admin rights)
- Look for your VPN app in this list and tick its associated boxes for Private and Public
- 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, it might be the reason why you keep seeing VPN error 806 on Windows 10.
Whitelist the VPN app in your antivirus
If you don’t have a third-party antivirus, it means that Windows Defender is in charge of your firewall settings.
So, if you already added an exception for your VPN app using the Windows firewall, you don’t need to go through this stage anymore.
Otherwise, fire up your anti-malware solution and make sure to add your VPN app to the whitelist section. It will stop your antivirus from blocking your VPN.
If you frequently encounter this problem, check out the best antivirus solutions with VPN.
Allow PPTP passthrough on your router
Access the admin page of your router and look for PPTP and/or PPTP passthrough settings.
Enable these options for incoming and outgoing settings to ensure that your home router doesn’t block VPN traffic when using PPTP.
An alternative solution is to buy a router with ready VPN functionality.
To recap, you can fix VPN error 806 on your Windows 10 computer by opening port 1723 over TCP and port GRE over protocol 47, or by adding an exception to the system firewall.
You can also whitelist the VPN app in your anti-malware tool and configure router settings to allow PPTP passthrough.
But a more convenient solution is to get a reliable VPN service like Private Internet Access (buy here).
