I've got the exact same problem too, for the past 2 days now. I've tried everything: Reset my router, deleted config files, re-installed Steam as well as DayZ. My internet connection is fine, downloaded DayZ (5gb) in 1 hour after re-installing it. I've also verified game cache on steam and have updates set to automatic. Also tried connecting to a few different servers, but still, nothing works. All my other friends seem to be able to play just fine. If anyone could shed some light on this issue it would be great to know what's happening.
