Cannot connect to ea server with battlefield 4 on xbox one! Need help.

I keep getting this message every-time i try to join the server titled Gamer gegen Rechts and its the only server that i'm getting this message from. i was in the server this morning but my mic wasn't working in game but it was working in party, so i left the server,  turned off my xbox one and and turned it back on. Now i can connect to the server, its the only server that metro 24/7 64 players and is hardcore. I'm hoping our probs are the same and i wasn't banned lol
