Plex doesn't see TNAS server (after password reset)

Plex Media Server NAS & Devices
10

Pointed at the IP address of your NAS?

Just confirming, since an unclaimed server will not appear when using app.plex.tv.

There is another option, involving editing the preferences.xml file for Plex Media Server.

This places your Plex Server in an unclaimed state. You can then reclaim it by logging in via http://nas_ip_address:32400/web.

I run Plex on a Synology NAS. I’m not familiar with the Terramaster GUI or other specifics, so adjust accordingly. Synology has a text editor in their web interface. If Terramaster has the equivalent, it can be used to edit the file. You can also edit it via SSH/CLI if desired.

  1. Stop Plex Media Server.
  2. Navigate to the Plex Data Folder.
  3. Edit the preferences.xml file.
  4. There are 4 values to remove. The are all of the form Name="Value"
    Remove the Name="Value" pairs for:
  • PlexOnlineUsername
  • PlexOnlineToken
  • PlexOnlineMail
  • PlexOnlineHome (if it exists)
  1. Save changes.
  2. Restart Plex Media Server.
  3. Point an incognito browser window at the NAS: http://nas_ip_address:32400/web.
  4. If the setup wizard appears, you can skip it, since your libraries, etc already exist.
