Hi, I get the error in the subject (see also below) after getting “✓ Ports 80 and 443 are free for use” during init. DNS is set up, SSl configured, website running from outside (test for yourself), curl output (truncated) added below, i.e. accessible from the box itself. I’m out of ideas what’s missing. Thanks for any insights.
PS. AlmaLinux 10.2 - 6.12.0-211.7.4.el10_2.x86_64

⚠ Port 443 of this computer does not appear to be accessible using hostname: metabolism.logophilia.eu
⚠ Connection to http://metabolism.logophilia.eu (port 80) also fails.
This suggests that metabolism.logophilia.eu resolves to some IP address that does not reach this
machine where you are installing Discourse.
The first thing to do is confirm that metabolism.logophilia.eu resolves to the IP address of this server.
You usually do this at the same place you purchased the domain.
If you are sure that the IP address resolves correctly, it could be a firewall issue.
A web search for "open ports YOUR CLOUD SERVICE" might help.

the issue above, you will need to edit containers/app.yml yourself and then type:
