FIX until BIS fixes finaly: http://feedback.arma3.com/view.php?id=22391
i have just updated my servers running on Linux via SteamCMD.
Now I and other players can't connect to the servers. We get kicked right after joining the server.
I've already reinstalled and updated the servers again.
It didn't help.
I've also set up an Vanilla-Server on a differnet machine.
While checking the installation I've found a missmatch between the versionnumbers of the server and client.
Ingame it shows the that I have the right game version (1.38).
