I tried joining via lobby, and he opened UDP router and even firewall. Website test says the port is open.

Hey folks, my friend tried to host a game and opened the Port 20595 as mentioned in the lobby, but i´m still not able to join. I tried joining others randomly to test it and it worked. The problem is just joining him. Are there any other known complications while hosting a game than opening Port 20595? Some people i talked to in lobby seemed to have the same issue. thanks in advance
