Help getting HQPlayer to work in NAA mode on Mac

Update: I tried getting Roon to work in RoonReady mode using my microRendu as the endpoint and it worked fine. It took some playing around with but ultimately I got it to work.

Now I have two Zones, 1) RoonReady and 2) HQPlayer. RoonReady works great, but when I try to play through HQPlayer in NAA mode, I get the same dreaded error message that others have reported "Transport: Couldn’t connect to HQPlayer”. I can play HQPlayer directly in NAA mode with no problem, but once I launch Roon and change to the HQPlayer Zone, it will not play.

Below is a screenshot of my Roon Preferences. My Mac Mini running HQPlayer has the IP address of 192.168.1.26.

Does anything look incorrect from what you can see?

Thanks in advance.
