Hello @Ethicaweb!
Just FYI: I moved your topic to the category “Apps & App Center” and tagged it with “nextcloud”.
I assume that we need to adjust the config.php file inside the Nextcloud Docker Container (switch in the container via univention-app shell nextcloud). Is that the one you modified? Can you give us the exaxt path to the file?
Best regards,
Michael Grandjean
