Nextcloud stuck in update to 23.0.4 and no longer accessible

-Nextcloud version _23.0.2
-Docker installed on Unraid
-NGINX Vers. v2.9.16

HAllo I wanted to update to 23.0.4 via the updater in the admin portal
The update has started up to the item Delete old data
There the update got stuck with a Red Cross
Have waited a long time, but Nextcloud is no longer started
Error message in the logfile: Could not open input file: /config/www/nextcloud/cron.php

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

<?php http_response_code(503); die('Update in process.'); I ask for forbearance if I have forgotten to share something. Can anyone help me?
