How access server settings after first run

I downloaded a new server software. For some reason I missed the initial setup and I can’t find a way to complete the initial setup. Also my hdhomerun is not seen in the app. Please help this old man. Not as sharp as I used to be.

Make sure to access your server locally, e.g. http://[PMS IP address]:32400/web while being on the same subnet.

That’s the way I access it. But no server configuration possibilities are shown.
