Why is my Minecraft Bedrock Realm not starting?

I've been trying my Minecraft for about 1 hour

Bedrock Realm starts, I've tried several times, but always the same message (see attachment)! Also restarted the game several times. Everything went well today at noon. Play the Windows 10 edition of Minecraft

Has the subscription expired? Or do you have no or bad internet?

The subscription has been running for over 5 months, and it shouldn't be because of my internet either. It was still possible today at noon.

I'm sorry, then I can't help you any further - Minecraft is currently pretty buggy when it comes to multiplayer.

Realms are actually completely bugged in Bedrock at the moment. I can't even upload a behavior package… But trzdm.

If everything went well at noon, then just wait until tomorrow or later, maybe Mojang is having server problems or something else.
