Critical Error: Failed to call 'Frontend' 'stop'

What happened?

Started Zigbee2MQTT with a fresh install. But It keeps crashing tried 1.29.2 and latest-dev. I get the following output:

Just figured it out: The actual issues is the failing mqtt connection. The error message is a bit misleading here(at least for me).

However, did this change somehow? Because mosquitto is in the same namespace as Zigbee2MQTT and it used to work by just setting it to "mqtt://mosquitto"(name of the service). Now it only works if I set the full name "mqtt://mosquitto.home-control.svc.cluster.local".

Fixed the error!

Changes will be available in the dev branch in a few hours from now. (https://www.zigbee2mqtt.io/advanced/more/switch-to-dev-branch.html)

That was fast 😀

Thanks for the quick feedback! 👍
