Apple TV Extension - Roon TV Remote

I needed to delete TV:Remote from my Apple TV last night and am now unable to properly configure it (I’ve been through this before…)

As I understand it, I need to add my Roon server’s IP address and port number so TV:Remote can find my server. In an earlier post, @gTunes advised that the port number can be found at “Web Display URL” in Settings > Displays. This is a screenshot of my settings:
Untitled
and this is the IP address for my Roon server:

I tried entering both the 127.0.0.1:9330 (which of course doesn’t look right) and the 192.168.1.244:9330. Neither one worked.

What setting do I need to change to bring TV:Remote back? Do I need to change (can I change??) the web display URL in Settings > Displays?

Thanks!
