Problems in to MC Realms Which I can Join But Cannot play

When I Log in to realms the screen "Loading Terrain" took like 1 min to log in and then it would not respond to the server and after a few seconds it would say "Connection Lost Disconnect" the server and I couldn't Join. Even if I keep on Joining
Its Something like this from older version but its on realms
