This worked for me.
If you’ve changed your password on Plex.tv, and things didn’t go well afterwards …
There is a similar method for other hosts:
On the server computer
Open a Terminal window / SSH into the machine / get into the container ,
(whichever case applies)
Stop Plex
Edit Preferences.xml
(Use the Linux text editor on the host itself.)
Carefully remove the following Name="Value" pairs
– PlexOnlineName
– PlexOnlineToken
– PlexOnlineMail
– PlexOnlineHome (if it exists)
Save the file
Start Plex
Keep the terminal window open. You will need it again momentarily.
On your computer
Open Claim | Plex
COPY the token given into your browser
Switch back to the Terminal session window
On the command line (where the server is), type:
curl -X POST 'http://127.0.0.1:32400/myplex/claim?token=PASTE_TOKEN_HERE'
Hit Enter.
Wait 15-20 seconds for Curl / PMS to talk to Plex.tv and setup new credentials.
As confirmation, the curl statement will look like this:
curl -X POST 'http://127.0.0.1:32400/myplex/claim?token=claim-xxxxxxx'
Confirming success.
You will be able to confirm the server is properly reclaimed and credentials are in sync when, after executing the curl statement, it responds with a stream of XML which ends in </MyPlex>
