I have a Govee smart kettle running through MQTT and Mosquitto broker. We just had a power outage at home (I know I need a UPS...) and while everything came back, the kettle is not available. I've tried starting Mosquitto and I just have no idea of how to reconnect this. Does anyone have experience wit this that can help me out?
I would initially do a full power down and restart of your networking equipment such as your router.
Restart your HomeAssistant server.
Restart your device.
Check the system error log for any relevant entries.

The MQTT Explorer app may be needed to verify if MQTT Traffic is getting through if the above does not isolate your problem.
