Cant log in

So, while i was messing around with the fill command and laying a bunch of TNT it caused the server to crash and Disconnect my gamertag. When i try to log in it says either disconnected from server or i have not been invited to play in the realm. I have tried hard restarting my systems and logging out. I found my Character on my friends Gamertag where I was booted from the server and seem to be there permanently. I'm not even entirely sure what else to do other than beg for help.
