AXIS M3115-LVE problems

I’m trying to connect an AXIS M3115-LVE camera to Angelcam – after installing and starting the app, it appears to crash with the following in the log file:

2020-09-21T21:03:45.751-07:00 axis-b8a44f036451 [ INFO ] angelcamconnector[0]: starting angelcamconnector

(This repeats forever, every 6 seconds.)

Anyone have any ideas? The M3115-LVE isn’t in the list of supported cameras, only M3105-LVE, but the architecture is almost the same (though based on ARTPEC-7 instead of ARTPEC-6), so I was hoping it would work.
