MQTT API just stopped working

[reneroth]

For whatever reason, the MQTT API just stopped working. Didn't change anything, tried re-authing, etc.
Web API works, but there are no responses coming from the device (A network protocol error occurred when communicating with the broker.).

This did simply not happen until yesterday:

[Roborock S8 Pro Ultra] Failed to connect (Unknown error.)
[Roborock S8 Pro Ultra] A network protocol error occurred when communicating with the broker.

The above exception was the direct cause of the following exception:

I do not believe this is an issue with this codebase, more likely something else I'm doing wrong, or something wrong with the device. The app was also broken, in that I could not enter the map view anymore (which relies on the MQTT data), but that was resolved by resetting the WIFI on the Roborock. The NodeJS implementation in a different repository shows the exact same behavior.

Did anyone encounter this before? What do?

It is likely you hit the cloud endpoint too many times (or you reauthed too many times)and are rate limited. Typically you can disable whatever script you have running for 3 days and then you will be fine

If you reset the device, you may need to get the user data and home data again if you have those cached

THANK YOU, it seems to have been some kind of combination of "silent rate limit" and "auth being messed up". What drove me crazy was that the MQTT commands that make the robot do something worked, only the ones where I expect to get info back did not work.
