Ignition and Maple System

I am using Ignition Edge as a MQTT publisher, Ignition Gateway as the MQTT broker, and I want to use a Maple system as a MQTT Client. Using MQTTfx as a tester I can see the info at the Broker. Having issues connecting with the Maple system even with it configured using the Sparkplug B encoding/decoding. Just wondering if anyone here had any experience with this kind of setup?

Any change you ever get an answers to your question?
