MQTT Connection to Broker Failing

[ST_10465152]

I am using ThingWorx version 9.3 with the MQTT Extension version 3.1. After configuring MQTT, the connection remains in a disconnected state, but it has been verified to be connected through a client tool.

Thank you so much, it worked! I was indeed using version 2.0 of the MQTT extension, and switching to version 3.1 still didn't resolve the issue. After reading the article, I cleaned the extensions in Tomcat, restarted ThingWorx, and reinstalled the MQTT extension, which finally fixed the problem
