Access through domain, 'untrusted domain' warning still present even after successful add to config.php

CAN access the web interface fine with local address.
Domain successfully points to the server, can go to the adress but shows the " Access through untrusted domain" page.

ADDED the domain to config.php and verfied it has been added with

’ nextcloud.occ config:system:get trusted_domains ’
Domain is listed alongside the local address (Which works).

Not using SSL cert until I can get HTTP working at least.

Running on Ubuntu Server 18 using a Snap. Been fully restarted.
Checking/downloading logs using the network web interface are completely blank.

Verified with command:

<removed by admin, shows sensitive data>

Did you find a solution?

Same issue with me. I am using localtunnel. Any solutions?
