wont let me join onto OP prison

i was on my plot and i started diging down and i think i reached my (dig down limit) and it disconnected me when i started falling.
and now when ever i try to join on op prison it disconnects me from the server! HELP!

D:

 

have you tried restarting mc

 

Most likely Internet issues

 

This might cause it

 

^^^^^^^

Maybe, the server console detected flying and kicked you for flying

 

It may be because the server is full which it has for the past week.

 

Yeah, i think thats whats happening

 

Resolved?
