I create a PPTP VPN in Windows 10 Mobile. When I want to connect, it shows this error:

A connection to the remote computer could not be established, so the port used for this connection was closed.

What is this error and how do I fix it?

  • This sounds like it is failing to connect to the VPN. Is that VPN server available from your phone? Are you on the same network? Aug 19 '16 at 1:07

This error indicates that the phone is unable to connect to the VPN server. Possible causes include:

  1. Your server may be unavailable. Try a connection using a PC.
  2. You're connected to a network which uses NAT. If you're connected to a Wi-Fi network, the router needs to support "PPTP pass-through", since your phone's IP address is not a public IP address and that does not work well with PPTP. This solution also applies if (1) fails above.
