For months and months and months I was able to play on any server i like, but the last week all of a sudden i can't connect to hardly any. 'Connection failed, error unknown' pops up. I have searched and searched for a fix for this and there seems to be none at all. I have tried everything to reinstalling the game to changing ip address and such.

Surely this is an issue to be looked at as when searching it seems to be quite common but no actual fix or anything said on the matter from nitrado/bohemia pretty poor i am unable to play the game at all now.
