I removed the auto ban, but if it happens again it might mean that your game files are corrupt and when you connect the server thinks you're trying to mess with it...Such an issue would prompt a fresh install of your BFV game.
You should be able to connect now, but if it happens again, I can provide a guide on how to completely remove & then re-install BFV.
Download and run it. It will provide us with your game Key-hash. Not your cd key, but you keyhash. I'll need you to email or direct message me your keyhash so I can check if it's not banned somewhere else.
