Had to log in to the server and do a global `grep` for the hostname on the file system and found an instance in a file called `app.yml` in a folder `/var/discourse/containers`. Apparently the hostname of the forum is _hard-coded into the application_ instead of being configurable.

Edited the file, and it still didn’t work. Did some googling and ran `/var/discourse/launcher rebuild app` and after a few minutes of downtime it came back, and appears to be using the correct hostname now.
