Hello Everyone!
I have a question, I wanted to host Discourse on Docker but… When I try adding a domain, It just errors and I can’t find out the right DNS for it.
WARNINGS:
WARNING: Port 443 of computer does not appear to be accessible using hostname: [forum.alsoftworks.net](http://forum.alsoftworks.net).
WARNING: Connection to [http://forum.alsoftworks.net](http://forum.alsoftworks.net) (port 80) also fails.
I hope someone could help,
Regards,
Slimy\_74.

Given that you have control ovrer `alsoworks.net`, you need to go to cloudflare and add an `A` record for `forum` that points to your VM. Make sure that it is DNS-only (gray cloud).
