Just uninstalled my OLD plex media server from one of my old pc’s. I reinstalled on the new PC. How do I get rid of these. I cant figure out how to create a new server or how to git rid of these.

If you accidentally delete an active server, this is equivalent to signing it out. To re-add it to your account, access it through its local IP address (e.g. http://127.0.0.1:32400/web if you’re on the same machine as the PMS; http://[PMS IP address]:32400/web otherwise) and sign it in via Settings > [Server Name] > General > Sign In.
After installing the Plex Media Server app, make sure you complete the setup of this server. To do that, open the bundled version of Plex Web locally (=from within the same subnet).
If the server is installed on the same machine, open http://127.0.0.1:32400/web, otherwise use http://[PMS IP address]:32400/web. This should bring up a setup wizard where you’ll be asked to name your server and to link it with your Plex account .
Once you linked the server to your account you can also access its content from other Plex apps linked to your account.
I take it you’re running that browser on the same host as your PMS?
Did you at some point already have another Plex Media Server running on that server?
