"Not authorized" to use my own on device server (MacOS)

Yes we can help. You’ve done a lot of strong things to fix it by the looks of the Article. That’s okay. Your server is still there., and we’ll get it back.

it’s very important to know a couple of things:
To get me your MacOS and PMS versions, run these two commands in a Terminal

defaults read loginwindow SystemVersionStampAsString
defaults read "/Applications/Plex Media Server.app/Contents/Info.plist" CFBundleVersion

You might only need to Sign Out and Reclaim.
You may also need to downgrade.
The decision is based on your versions.

I wrote up How To Sign-out PMS on a Mac, Downgrade and Reclaim if you want to read ahead.

The Howto shows the exact steps for using the claim-xxx code when you get to that step.

So you can see where the claim code goes, here’s an example:

  • You go to Plex | claim and you’re given the token claim-12scoobydoo34dogdoor
  • You COPY IT and
  • In a terminal on your Mac issue the claiming command with that token
curl -X POST 'http://127.0.0.1:32400/myplex/claim?token=claim-12scoobydoo34dogdoor'
