Linux Mint & Apache configuration

[Huw Morris]

I'm new to Jellyfin, as a Plex refugee.

I'm running linux Mint 22.1. I have managed to install Jellyfin, and I can access it at DOMAINNAME.duckdns.org:8096.

I have installed Apache, but I'm totally lost as to how to get reverse proxy or https working. 
I am attempting to follow the guide at: https://jellyfin.org/docs/general/post-i...ced/apache but it's really not clear at all. I've added the section into /etc/apache2/apache2.conf, replacing all the DOMAIN_NAME with DOMAINNAME.duckdns.org, and SERVER_IP_ADDRESS with 192.168.1.193 (which is the internal IP of the server).

I have a certificate at /etc/letsencrypt/live/DOMAINNAME.duckdns.org, which I apparently installed a couple or years ago in my last failed attempt to get any of this working. Certbot says the certificate is still valid.

What else should I have done to get this working? What address should I be using to try and access Jellyfin?

https://DOMAINNAME.duckdns.org appears to redirect to http://DOMAINNAME.duckdns.org, so Apache is clearly not set up properly. How can I troubleshoot this? Please let me know what further details you need to help me with this!
