FAQ 31: Reset / Reclaim PMS on DSM 7 (Not Authorized - Locked Out)

  1. Uninstall the app - Use the first radio button (KEEP) option.

  2. Reinstall the same, or newer, SPK (package) version.

Now let it install and get updated credentials for your server.
(Getting new credentials takes a little longer than normal install – 10-15 seconds)

If networking is correct, it will complete and show ‘Claimed by: YourPlexUsername’

You may now open the server normally.
