Being kicked from a game server with 'Connection Interrupted' message indicates a client-side connectivity issue with your PC and the EasyAntiCheat network. EasyAntiCheat uses a standard HTTP connection to client.easyanticheat.net:80.
Ensure that your anti-virus and/or firewall software is not blocking the connection to this DNS address.
When using Steam, always launch the game through Steam and not directly from the game directory. Otherwise the game may start without anti-cheat protection, thus failing to authenticate with game servers.
