i am experiencing a similiar issue, i can log in to the game but everytime i try to login to a server particularly in the NA data centers/servers i get disconnected before i even get into the server i'll be in the loading screen but then all of a sudden it will say i am disconnected from the lobby or server. i tried my character on a japanese data center/server and it took me right into the game no problem so it must only be happening in NA data centers/servers
