My Realm experiences multiple errors

Multiple errors on my Realm.

"It is not possible to connect with the world"
On several occasions in the last hours, I and the members of the Realm were not allowed to enter it.

World was re-established unexpectedly.

Upon entering, we noticed that the world had changed for a new one started from 0 and with a different seed.

Backups failed.

When trying to return our world to a version before this change, it indicates an error.
