Error when setting Up Conbee2

[seresheim]

Is this a common error when trying to set up ZigBee HomeAssistant Automation or a new one?

2025-10-19 11:27:36.764 ERROR (MainThread) [homeassistant] Error doing job: Task exception was never retrieved

It appeared while I was doing the initial setup as seen in the image below (sorry it's in German):

I run home assistant in a Docker container, but the device /dev/ttyACM0 is provided (via --device parameter in the docker run command).

This error says that the connection to the radio was lost and a pending request was cancelled. Does the radio work?

[seresheim]

The radio works perfectly fine.
Is the deconz service maybe interfereing with it?

ZHA and Deconz can't both be running at the same time so if you have one, you should get rid of the other.

Just did that, then I got one step further, but now I have this new error message:

The deconz gateway, however is now disabled.
