Hello @Todd_Haugen, if your core is up and running, open the app on the remote. If you remain on the “Choose your Roon Core” screen for 60 seconds, a “help” button should appear. If you tap there, you should be presented with the option to enter the IP address of the core manually. You can also try the multicast broadcast IP (255.255.255.255) if the core IP doesn’t work.
