I’ve recently installed Discourse to a Ubuntu Focal Fossa VPS and it works great, however I’m struggling to overcome some URL peculiarities.
The following is the behaviour I am seeing (in Safari). I have A NAME records for @, WWW and * created in with my registrar.
example.com [displays Welcome to nginx! page] FAIL
www.example.com [redirects to https://example.com] PASS
http://example.com [displays Welcome to nginx! page] FAIL
http://www.example.com [redirects to https://example.com and works fine] PASS
https://example.com [works as expected, doesn't redirect] PASS
https://www.example.com [errors with 'This Connection is Not Private' browser message] FAIL
I would like my installation to be at the root/apex so I entered example.com at setup.
Hi @Falco, thank you for your reply. Not to my knowledge no, the image from the VPS provider is just called “Focal Fossa Clean OS” which I assume means it contains no third party tools.
This is just straight out of the box using the “30 minute” install route published.
sudo su
wget -qO- https://get.docker.com/ | sh
git clone https://github.com/discourse/discourse_docker.git /var/discourse
cd /var/discourse
./discourse-setup
Sure thing, thank you. Would my domain having a weird TLD cause any issues? (it’s a .community).

Ok well I’m clearly a moron. Tried on my phone over 4G (to check local DNS), all those URLs worked fine. Reconnected to WiFi, all work fine. So I then cleared the cache of Safari on the desktop and boom — everything works there too.
It must have been from when I was initially testing the host and the cache hasn’t flushed since. Thank you so much for your help to troubleshoot and sorry for taking up your time.
fwiw ho appena riscontrato lo stesso problema oggi con Ubuntu 22.04. La cancellazione della cache di Safari e l’aggiornamento hanno risolto il problema.
