After upgrading to Umbrel 0.4.1 Nextcloud stopped working and showed this message:

> Access through untrusted domain
> 
> Please contact your administrator. If you are an administrator, edit the “trusted\_domains” setting in config/config.php like the example in config.sample.php.

How can I fix this? Thank you in advance!
