My game crashes when I try to connect to my server. I have tried restarting the server. restarting the client machine. reinstalling java on both, client and server machine (both use open java-8) 64bit as it is 64bit Ubuntu 15.03 I did app_update 380870 validate on the server machine (to check wether files were corrupted). My ports are forwarded as follows: 16261:udp 16262-16330:tcp also steam port is open I can connect to the server and I can create a character, however on loading map it just crashes. I can connect fine to other servers. EDIT: in the server console I can see that everything runs fine till port assignment: 16262, client seems connected fine. then connection closed: reason=1 port=1 disconnecting client ID auth failed sending ticket response: 4
