So this is sending me absolutely mental, i had a server up and working and was playing with friends, then there was an issue where the server list was listing it as full when it wasn't so one of them couldn't join, then when i went to restart the server it's completely stopped working, i've port forward and all that, and for some reason the server appears twice on the master server list. I have no idea what's going wrong, i tried restarting and reinstalling the entire game.

For reference it says it's successfully authenticated and then times me out.
