Freigabe funktioniert nicht - Datei nicht gefunden

Hello,
my problem is, if i share a folder as a link, the link will not work. I’ve done this many times before but since a while it does not work. (no idea what changed)

Nextcloud version: 24.0.5
Operating system and version: Debian 11
Apache or nginx version (eg, Apache 2.4.25): replace me
MYSQL: 10.5.12
PHP version (eg, 7.4): 7.4.26

The issue you are facing:

Is this the first time you’ve seen this error? (Y/): Y

Steps to replicate it:

  1. share a folder (simple read_only - no psswd no experation date)
  2. copy the link given
  3. add it to any browser, device …

The system is running in a VM on a proxmox server.
Proxmoxserver —> VM (debian) → Docker container with mariadb + nextcloud

no entries at the error log or any obvious problems.
old share links still work

uploading files works and they will be shown on all devices but updating nextcloud 24.0.4 —> 24.0.5) will be done correct and without a problem, but restarting the docker container the changes will be gone and v. 24.0.4 is there again

thanks for you help

would you please be so kind and adjust the title of your thread to english? you can keep the german version as well… but we prefer having english titles in the international part of the forum…

so it could look like this

share doesn’t work - file not found / Freigabe funktioniert nich - Datei nicht gefunden
