LAN Only, Self Signed SSL Cert / HTTPS Help

[Zer0CoolXI]

Hello All,

I just finished setting up Jellyfin in a Proxmox Debian 12 LXC container. All good.

I am now trying to setup HTTPS. My setup is LAN only, no remote access. Just want to do it for piece of mind. I'd prefer not having to use something like Lets Encrypt and/or reverse proxies.

I just want to generate a simple self-signed SSL cert and enable HTTPS on Jellyfin.

I followed the steps here: https://claytonerrington.com/blog/jellyfin-and-ssl/, replacing the FQDN with my own internal FQDN for jellyfin...using a ".lan" tld (I know).

I have a 'jellyfin.pfx' file in '/srv/jellyfin.pfx'.

In Jellyfin, I have on the Networking settings page:

• Checked "Enable HTTPS"
  
• Under "HTTPS Settings", "Custom SSL cert path", entered /srv/jellyfin.pfx
  

Settings saved, server has been rebooted.

going to "https://jellyfin.domain.lan:8920" results in a problem loading page/unable to connect result. http on port 8096 works as expected

I am not sure where to go from here. Either I am missing a critical step in the process or the guide I followed lead me astray. Any help would be appreciated. Thanks
