Permission denied: Can’t write or read changes with clients

Hi,

I don’t have writing access to my data (and I can see no changes) since about 10 days, when I uninstalled something else (homebridge on docker). Nextcloud is installed on an external USB-Drive and has 3 users. The data-path is /media/myCloudDrive/ncdata/ncp/files/.
To check the rights I used

ls -ld /media/myCloudDrive/ncdata/ncp/files/
And got back
drwxrwx--- 1 www-data www-data 106 Jul 31 2021 /media/myCloudDrive/ncdata/ncp/files/

For getent group www-data
I got
www-data:x:33:pi,jenny,muelli,ncp

I already updated to 1.50 and tried the „permission fix“-option in the panel (ip:4443)

What is wrong?
Thank you for helping ideas and sorry if this topic is double- I didnt find a solution for me here…

Please:

  • post the full error message (log entry)
  • confirm the permissions on all the parent folders above /media/myCloudDrive/ncdata/ncp/files

Hi, here the log-Message (hope I got the right, I forced a mistake with creating an empty document)

And the permissions:

I solved it: A syslink stopped the sync. I removed it and scanned with sudo -u www-data php /var/www/nextcloud/occ files:scan --all
