Can't access Nextcloud after upgrade

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!

After update trusted domains config reset to deafault. Follow this guide:
