Hello,  
I am trying to use the MQTT Engine module in Ignition. My Ignition version is 8.1.41, and the Engine module version is 4.0.21. I am attempting this locally. I have a local Mosquitto broker, which is working without issues. I can subscribe to incoming data using MQTT Explorer. However, when I try to perform the same operation in the MQTT Engine, I receive a “Not Connected” error. Could you help me understand why this is happening?
