I’ve done the whole nine yards this morning to log into a server my bud and I started on yesterday and put many ours into. Official server #2510 PvP. I have reset my ip, router, and game as well as xbox and still no luck in getting into this server. I really enjoy the game but it bugs me I can’t get into a server I put hours into. Our clan is god kings and my name is ConjuredWish.
