Client - Error transferring

Hallo zusammen,

eines unserer Clients bekommt die Meldung:

Die Datei "ING Diba" ist auf dem Filesystem auf dem Server und auch nicht auf dem Client vorhanden.
Der Server und der Service sind online und funktionieren einwandrei.

Please have a look in the server error log - this should reveal the reason.

So - this folder no longer exists - was there some modification on the server? Did somebody accidentally delete it?

To finally resolve this - run the occ command files:scan - please read about it in the official docs.
