Server Disconnect Every 10 mins

I have been playing on this Realm without any issue for over a year now.  Just in the past few days it has started disconnecting approx. every 10 mins.  (I've timed it).  I have tried logging in with both Windows and Xbox versions of the game.  Both have the same issue.  I have downloaded the world and restored it thinking that might help but it does not.  

 

Please advise.
