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.
