Summary of the issue you are facing:

When the user leaving a shared folder/file, the files within that folder cannot be restored by the recipient, the access to the shared content is lost once the share is removed.

Steps to replicate it (hint: details matter!):

  1. Navigate to a shared file or folder

  2. Click on “Diese Freigabe verlassen” (see Picture)

  3. Then go to the “Gelöschte Freigaben”

  4. Then try to restore the shared file/folder leads to an error (see second Screenshot)

Web server / Reverse Proxy

The output of your Apache/nginx/system log in /var/log/____:

-

Configuration

Nextcloud

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

-

Apps

The output of occ app:list (if possible).

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
