After entering the nether, the realm, which previously did not have connection issues now disconnects frequently (every 2-3 minutes) when in the nether. The game also refuses to reconnect, indictating the realm cannot be connected or disconnected from server, for a few more minutes after disconnect. Sometimes removing mcpe from memory is needed to fix this problem. This issue disappears when the player returns to the overworld, suggesting it is a nether specific problem.
