Mosquitto broker stopped working in Hassio

Question

My Mosquitto broker stopped working and I think it might have something to do with me trying to use the same Raspberry Pi to run Tuya Convert.

I know Tuya Convert installs a bunch of stuff and I'm guessing one of those screwed my MQTT Broker, probably by running some other mosquito instance in the RPi or something like that. But I don't know what to uninstall without screwing it even worse.

I'm running Home Assistant supervised on Docker. On a 4Gb Raspberry Pi 4 Model B with Raspberry Pi OS.

These are the logs

Hassio general logs:

Unable to connect to the MQTT broker: Connection Refused: not authorised.

Please let me know if there's any other information or logs I can provide!

Answer 1

Probably the easy way to solve this would be proceed with a fresh reinstall.

Reinstalling the Mosquitto broker with all its components and settings you need will restore previous configuration and address the problem.

What is probably happened is Tuya Convert reinstalled and configure some of the Mosquitto MQTT Broker component changing its corresponding Integration.

Once you reinstall/reconfigure/start Mosquitto, after having done the above, you should see a successful connection in the logs.
