Hi @samothx
I followed a fork in the Electron project for Debian Buster, and that seems to be working without issue now. The Pi4 will also now connect to the WiFi network first try and load everything perfectly.
The only remaining issue is that Balena’s WiFi-Connect container does not create a wifi connection on the Pi4 when a wireless network is not found.
I apologize for jumping around these three issues, but I was having difficulty isolating the problem. I have granted remote support for the new application with the new Buster Pi4 Electron container.
