This is interesting. I have another question on the forum regarding my config nodes ([Question about MQTT config nodes](https://discourse.nodered.org/t/question-about-mqtt-config-nodes/6439)), which may be the problem.

My MQTT broker is on a separate Pi, but according to the config tab, I have the broker defined multiple times. And I don't know why. Could this be causing the problem? (My client ID is always blank, but that's no guarantee that multiple config nodes could not auto-create the same client ID).
