My Mosquittobroker add-on doesn’t seem to start, it’s not turning green. However, in the list of available add-on items, it is shown as green, But the MQTT broker service is not working despite being configured properly.

It’s completely empty even after refresh.
If you start the add on it’s log should populate as it starts.
What about the hassio log then. Seems like it isn’t actually starting.
Might be worth it to uninstall reinstall and double check your config.
