stuck at the “Joining Session” screen or receive an error message.
 

PROBLEM:
I am hosting a Delta Force Black Hawk Down game on NovaWorld and people are able to see it in the game lobby, but when they attempt to join they get stuck at the “Joining Session” screen or receive an error message.

RESOLUTION:
If you are hosting the game from behind a router and you have not setup port forwarding your game will be visible in the NovaWorld game lobby, but will be inaccessible. You will need to configure your router to forward all incoming traffic on UDP port 17479 to the internal IP address of your computer which will be hosting the game.
