Realms keeps disconnecting me.

The issue happens at various times, but the outcome is always the same. I try to enter my friend's minecraft realm, and i am unable to break blocks, and everything stays completely still until i get disconnected from the server, usually with the error code "java.io.ioexception". I've tried every possible solution available but none were successful. My friend's minecraft name is Ramironga4 and mine is JustFede8. The server, regardless with how much time it takes, ends up kicking me from the server and giving me an error code as mentioned above. I've been trying to play with my friends for about 5 hours and i've failed in every attempt i made.
