Problem when i join other realms

One day i joined my friends Realm that i have played alot on without problem before, one day when i joined i logged in and after a few seconds i got kicked and it said server closed. But the server was never closed and was still up so i reconnected and the same thing happened. I gave up and turned off my computer and the next day i tried to log in and my friend was online too, I logged in and after a few seconds both me and my friend got kicked and it said
Internal Exception: java.lang.StackOverflowError and i searched around but only found a fix for when you are a server host but not a player. so i would like some help or something that could help to fix the problem. Thanks
