Fixes I've tried:
-Reinstalled the game
-Changed firewall/antivirus(Kapersky) settings to allow DayZ and BattleEye through.
-Fiddled with Windows compatibility
-Tried the Reset Winsock trick
-Fiddled with server filters
-Looked through each tab
-Attempted to remote connect to a server with an IP
-Attempted to join my buddies through the "join game" option on steam
-Tried joining a different router
-Restarted computer
I have seen one man solving this by reformatting his Windows. I have not tried this.
