Icloud Synchronisation funktioniert nicht mehr HTTP/1.1 507 Insufficient Storage

[Mario1010]

Seit gestern funktioniert die Synchronisation mit Icloud nicht mehr.
Es kommt der Fehler HTTP/1.1 507 Insufficient Storage (siehe Bild).
Der Fehler tritt auch an einem anderen PC auf.
Ich nutze EPIM 11.5.2. Ein Update auf 11.8.2 bringt keinen Unterschied.
Die Icloud-Synchronisation löschen und neu anlegen bringt keinen Unterschied.

The iCloud server reports that there isn't enough storage left in your account. Please check and free up some space. Thank you.

That can not be it.
Icloud has 1800GB free.
I tested another Icloud account (Icloud2).
Doesn't work either (see picture).

I suggest you contact iCloud support regarding the first error message about insufficient storage space, as that's the error the server responds with and we cannot influence it.

As for your second account, there's a different error, and we'd need to get the sync log file to provide more information. Please obtain one by going to Tools->Options, selecting "Logs Folder," and looking for the file that begins with "iCloud." Thank you!
