You're running Supervised so it's likely that your Docker container doesn't have the serial port passed through correctly. ZHA can't connect to your radio.

Maybe this is because I installed DeConz to see if it could resolve the issue I originally had - Network Formation Refused. I uninstalled it and now I am getting the Network Formation Refused error again. I have tried moving the Conbee II further away. It's now 1,5 meter from anything else. This problem just occurred when I wasn't even home and was not related to any other changes to the system.
