Theoretically, it is possible that your issue is caused by a 'faulty' key. If you are using one which has been published with other leaked/ stolen/ otherwise illegally obtained keys and subsequently banned by TaleWorlds, it possible that you keep being disconnected from game servers by the Master Server. Make sure to acquire a legit serial key in order to play the game. You can obtain one on, for instance, Steam or GOG.
