I have 1,850 of these events in the last 24 hours. It doesn’t negatively impact my Plex experience, but I’m curious about how I “fix” it.

I routinely access my Plex UI via FQDN.

Add your FQDN (in a P12 file)

  • Cert
  • Key
  • CA

to PMS so it recognizes it

You then add your P12 file path in Settings - server - Network - Show Advanced
