I have exactly the same problem, since the fall patch I can not connect to the EA server with my 2nd XBOX. I can play BF4 on one XBOX and COD on the other one at the same time without any problem. But I can only connect to the EA server with the FIRST XBOX I turned on. The second one will say it can not connect to the EA server. I am searching on the internet for a long time and everyone is trying to help with thing like IP adresses and port triggering, but my internet and router settings are good...It has to be something with EA...
It's driving me nuts...
