internal exception java.io.ioexception an existing connection was forcibly closed by the remote host

This happens when I have been playing on the realm for a few minutes. I have tried everything to update, re-install minecraft + Java and some different solutions on YouTube, but nothing seems to work.

can you help me? I simply cant play realms, and that sucks.
