Brand new SkyConnect v1.0 with stock firmware keeps looping between Failed setup, will retry and Initializing

[jiriappl]

Describe the issue you are experiencing

Just got a new SkyConnect with stock firmware and connected it using the provided USB extension cable to my HA install.

Alas, SkyConnect under ZHA keeps looping between Failed setup, will retry and Initializing, and does not seem to complete the initial setup.

I have tried to reboot HA, use different USB port and different USB cable, no change.

HA config:
HAOS latest bits, running on Intel NUC.

This is an issue in HA core and not related to any addons, thus this is the wrong place to report this.

You should open an issue on the below repo instead:
