SOLVED: Can't upload files on Seafile Server (Raspberry Bullseye)

I have no upload rights on my seafileserver v9.0.2.
If I try to upload a file I got a networkerror output in the upload window.
Also if I try to change my Avatar it notify ma that changes are saved but I see a missing image.
I have no idea where I have to start to investigate where the problem sourced.

With this tutorial I saved my seafiel data also on a external harddisk: Seafile Daten auf externe Festplatte speichern - StephansNet

EDIT: It seems that the problem was solved. i have no idea what I have done to get it to work :slight_smile: .
