How can I fix VPN error 806 in Windows 10?

Conclusion

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. 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. More about PIA:

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. 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. 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). Which of our solutions worked for you? Do you have any other suggestions?
