The issue you are facing:

Is this the first time you’ve seen this error? Y

Steps to replicate it:

No idea whats going wrong here. I Configured nextcloud according to the official documentation with nginx as the reverse proxy, using https with letsencrypt (certbot) on the nginx, and https from https://mydomain.something to the server running nextcloud

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

<?php
$CONFIG = array (
  'apps_paths' =>

I am unsure exactly as to which logs to include here. If they are needed please tell me exactly which ones are needed :slight_smile:
