Cannot access realms server

Today I tried logging into the realm and it says unable to connect to the world I tried many times restarted Xbox and even cleared cache but it says the same I tried joining servers and they got joined easily but I cannot join the realms server. I even used many devices to login and asked some of my friends to try to join the server but none of us were able to get in.Everytime It said Unable to connect to world. when you press on join realms it says loading and then it goes onto loading resources and after a few seconds the error pops up
