Our ArmA 3 testserver was offline for the last weeks. The hoster nitrado had problems that aren’t solved yet. The last week they found a bugfix: verifySignatures=0. But this opens all doors for hackers. Thus we decided to host the server by ourselves. Therefore we rent a server at netcup.
If you got the same problem, don’t set verifySignatrues=0 and switch to another hoster.
Our testserver is now back online.
