SOLVED: Ubuntu 20.04 Plex Media Server not accessible on app.plex.tv

Plex Media Server
1

Server Version#: 1.31.2.6739
Player Version#: N/A

I have created an Ubuntu PMS running in docker. I had run this on my Synology and copied the install. It was finding it on app.plex.tv but now no longer is doing so. I have signed out of app.plex.tv and the server then went to the server https://<ip address>/web and signed in using my plex pass login. I can access the server (when I go to settings there is a drop down listing the server name and “nearby” and an orange checkmark (there was a green icon earlier). When I go to authorized devices my server is NOT listed. I go to app.plex.tv and it only lists my old server (which if I turn it back on it works fine). Is there a way to get this server recognized?

Is the server claimed?

Go to http://pms_ip_address:32400/identity.

Part of the response should display claimed="0" (unclaimed) or claimed="1" (claimed).

If unclaimed, go to https://pms_ip_address:32400/web and login.

Then Settings → Server_Name → General.

Claim the server.

It says yes however when I look at the “machineIdentifier” field it has the same number as my old server (I copied over the Preferences.xml. However if I use the MachineIdentifier, ProcessedMachineIdentifier and AnonymouseMachineIdentifier from the Preferences.xml and restart the server and go to the Identity page it has the same machineIdentifier value in the returned value.

I figured out the issue. I had been messing around with Plex in other docker containers and there was one running that i didn’t realize was running and that caused the conflict. Once I shut that one down the original server was found again and all was right with the world.
