1. I join the realm
2. I fly in the air with my characters head shaking
3. mobs start to load in and then the rest of the world
4. I can't do anything, it is like time just have stopped and only i can walk around.
5. A crash message comes up with the text "Internal Exception: java.io.IOException: An existing connection was forcibly closed by the remote host"

I have tried restarting minecraft and restarting my computer but i still have this problem. I have even tried to change my texture pack to the default one but it doesn't work.

I don't have any mods or anything like that.

This problem has occurred my friend as well so i can confirm that it is not my computer that is the problem.
