Hello,
after a Servercrash I want to restore my nextcloud-installation on my new server but it fails when I want to join the nextcloud app. The failure in the log-file is:

I copied the old nextcloud directory to /var/lib/univention-appcenter/apps/ and imported the whole nextcloud database. After that the docker image started normaly but I could not join it now. Any ideas what I can do?
