I’ve been using PMS on my Synology NAS for years, but that device is nearing EOL so I wanted to move Plex. I’ve now installed PMS on an Ubuntu machine
OS: Ubuntu 22.04.1 (desktop, not server) VM on a Proxmox server. VM has 4 cores, 4GB of RAM
PMS version: 1.30.0.6486. Installed from the Ubuntu software Store (it’s a snap package)
Plex is up and running. Since I want to be able to use Plex from outside my home network I’ve configured Remote Access. That’s also working.
The problem is in installing a SSL certificate. I followed this guide. Although the installation seemingly went fine (an attempt to reinstall the certificate with certbot confirmed that a certificate was already present), no certificate is shown in a browser windows.
I’ve converted the certificate into PKCS#12 format, using the command shown in the guide, and input the data in Plex, using the password created when installing the certificate at ‘Custom certificate encryption key’ and my domain at ‘Cutsom certificate domain’.
Since this is a snap package, Plex is installed in /snap/plexmediaserver. Not in /var/lib/plexmediaserver. Not certain if that would matter.
Is there anything I’ve done wrong? Anything I can do to diagnose and solve the issues?
Any help would be greatly appreciated!
