Plex Server not seeing Server

New user here, and I have the same problem with a freshly installed Linux server: just like in the image above my own server’s web interface always asks me to install Plex Media Server…

I have already tried the suggested remedies:

  • signed out from Plex account in my browser, both in the web app and in the local web interface
  • stopped Plex Media Server
  • uninstalled Plex Media Server and purged all data (verified)
  • reinstalled
  • started Media Server
  • accessed local web interface, logged in with my account
  • under Your Media I see … “Get Plex Media Server”

No matter what I do, I always get the “Get Plex Media Server” page…
