If you’re getting Connection failed with error 800 message, we advise you to check your router and firewall settings. According to users, you need to allow for PPTP and/or VPN to pass through TCP Port 1723.

In addition, GRE Protocol 47 must be opened for PPTP VPN connection. After making those changes, check if the problem is resolved.

Some users are also suggesting to temporary disable your firewall and check if that solves the problem.

If the problem is fixed after disabling the firewall, it means that there’s a problem with your firewall configuration.

We have to mention that you should never keep your firewall turned off because it makes your PC and your network vulnerable.

If this problem is caused by your firewall, turn the firewall back on again and check its configuration.

It’s worth mentioning that other third-party security software can also cause problems with VPN connection, so you might want to temporarily disable your antivirus and check if that solves the issue.

We also advise you to check if the router or firewall supports VPN connections. Some devices don’t work with VPN connections, so you’ll have to install a firmware update in order to use VPN.

In addition, be sure to check if the router supports PPTP Pass-Through.
