AppLab 0.8.0 stuck in "configure board" mode

AppLab 0.8.0 on Windows 11.

Uno Q connecting via a USB-C hub which has gigE and via WiFi (the Debian side has two IP addresses - I can SSH to each one)

AppLab had connected successfully over gigE when I first tried it out, but after a reboot, it keeps going back to the setup, and there doesn't appear to be a "Stop trying to setup" button.

In the lower left I can see that it has a "rover" board, with a check mark next to it. I just can't get AppLab to switch to it and start showing me the Applications and Sketches that I've been experimenting with.

No ideas on how to get AppLab on Windows connecting to a remote Uno Q out of this configuration loop?

How are you configuring the Ethernet interface?
