Raspberry Pi4 Cloud Mount SSD failure Debian

Screenshot 2022-02-24 211719.jpg
I have a nextcloud server installed on the raspberry pi4. the latest version.
I formatted my ssd to ext4. then mounted it on /media/ssd . I then wanted to add this to nextcloud via external storage. Unfortunately nextcloud does not recognize the path see picture.

Have also already tried a folder created /media/ssd/data and then this path specified unfortunately without effected…

But before I also tried /media there next cloud recognizes the path but this is not the path to which my raspberry is attached but the internal memory

what am I doing wrong ?

isn’t it a local storage since it’s mounted to your system already?

Logfiles? The folder needs permission for the www-data user…
