Can't connect to any servers

Just recently got the game, as of yet have been unable to play it. Every time I try and connect to a server, I get the error message Disconnected: EAC: Unconnected. I have tried everything I can find online, including turning off my firewall and antivirus, and nothis has worked. I have tried on about 5 different servers under each category: Official, community and modded. any help would be appreciated
