Bug Minecraft

Hello, For some time I have a message telling me that I cannot connect to realms, server. This one explains to me how should I solve this, but I have tried everything but nothing works.
I have: uninstalled and reinstalled, I do have an Xbox Live subscription, I have a fairly stable wifi connection, I tried to solve this via the site: aka.ms/MCMultiplayerHelp but I can't do it.
I ask you for help to solve this problem because I would like to be able to replay on my favorite servers.
