WSJT-X Radio Connection status shows RED, but Test CAT is green & PTT activates transmit

I've not had success in debugging this. I am using N1MM (latest version) and WSJT-x (v 2.6.1) with SmartSDR (v 3.4.24). The Test CAT button is green. The Test PTT button will put the radio into transmit. I operated during the recent ARRL-digi contest. WSJT-x would decode signals, and I was able to transmit.

But WSJT-x Radio Connection window showed red during the contest and continues to show red (radio not connected). I attached an image of the various screens which I think show the condition. I must be missing something somewhere but can not put my finger on it.

One other thing I noticed which may be related, maybe not. I have 'Log Automatically (contest only)' checked in WSJT-x, but I was still presented with the window to confirm logging each contact during the contest.

This is puzzling to me. Any thoughts?
