I assume you’re setting up a new server?
In order to complete the setup you need to open your Plex Media Server through its local IP.
If you’re on the same device… open http://127.0.0.1:32400/web in your browser. If you’re on a different machine inside your home network, use http://[PMS IP address]:32400/web instead. This will bring up a wizard/dialog where you can name your server and link it to your Plex account (as well as creating your first libraries).
Once you “claimed” your server (=linked it to your Plex account), you’ll also be able to access it from other Plex apps or via http://app.plex.tv/desktop.
My issue is I download the server but every time I go to pull up the + Your Media it asks for me GET PLEX MEDIA SERVER. I never have the option to create a name for the library or add anything to the library. It always takes me to GET PLEX MEDIA SERVER. I’m on a new MS 365 HP Laptop if that helps
Are you accessing the newly installed server from within the same subnet (or the same machine), using the bundled web app (e.g. http://127.0.0.1:32400/web while in the same machine)?
Did you previously run a version of PMS on that machine with a different Plex account?
