Thanks for the info. That sounds correct.

Try the following: Synology FAQ 31: Reset / Reclaim PMS on DSM 7

  1. Uninstall Plex Media Server. When presented with an option, choose Uninstall Only.

  2. Re-install the same version of Plex Media Server. Use the Plex Claim Token option.

You should see a “server successfully claimed by …” message.
