MQTT Troubleshooting

[Santiago Fernández]

I'm trying to configure a connection with Azure IoT Hub using the MQTT protocol with no luck. I need to configure the broker using the 8883 TCP/SSL with CA Certificate. I provide the correct certificate of the root CA but I always get the -1 status code (Cannot connect to broker. Check communication parameters) in the broker.
I checked all the communication parameters and tested with a MQTT client (MQTT.fx) and I was able to connect correctly to the Azure IoT Hub. At this point my question is, is there any way of getting more information about which communication parameter is failing or getting more information for troubleshooting?

Thanks in advance
