Message broker (MQTT) connection issues

Thanks Gabriel for the explanations.

The web portal will essentially spin the color wheel forever, and upon initial refresh, I see the same error message like hx244808 as well as “error downloading data”. See below image for the Device widget. This same scene appears no matter the web widget (Account, Controls, etc).

I have seen these exact behavior across three different internet connections and computers. I have tried hard refreshing the browsers on all three, but there is no effect.
