was successful after initial setup.

What Debian commands can be used to probe and test to identify the root cause of the problem?

As indicated at

The trusted_domain configuration directive in the config.php file tells nextcloud what domains (host names) this nextcloud instance is known as.

If you access it as and is not among the trusted_domain list, you’ll get that error message. So you need to edit that configuration file, to add that domain name.
