'Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host

I am currently unable to play on the Realm that bought in order to play with friends. Everytime I load into the realm after around 10 seconds I get kicked from MY SERVER with the error message "Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host." This is incredibly frustrating and everything I have done to try to fix this has not worked.
