VPN ERROR 806

Buy VPN service

Solution

Verify that your router allows VPN pass-through. Switch to other VPN connection methods, especially to SSTP if available. This error means that your internet connection or ISP is blocking some aspect of the VPN connection.

 

Detailed description

The most common cause for this is that there is at least one internet device between your computer and the VPN server is not configured to allow GRE protocol packets. Verify that protocol 47 GRE is allowed on all personal firewall devices or routers. If you have a router/firewall, make sure you open TCP Port 1723 and UDP 1701
