SOLVED: Nextcloud - Service Unavailable

Since last update of FreedomBox I see this message when tying to access Nextcloud:

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Apache/2.4.62 (Debian) Server at permondes.de Port 443

The Android App says the server is in maintenance mode.

Restarting FBx did not help.
Any ideas?

After todays update and a “repair” via plinth, the service is available again.
