Okay so I wanted to play with my friend and I bought an 90 days realms for it.
as soon an hour pass we start to get this massage " Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host"

I didn't do a thing to make it happen, and I tried to change settings with java from ( People who try to solve it in youtube and show a guide for it)
and I read the comments here about it and I don't understand why does it happen in the first place, but never mind that.

Just explain to me why does it happen if you have any clue and fix it please, because I can't play other wise with my friend all though I wanted to.
I bought the 90 days deal for realms ( just an info ).
