Bridge Building – Mosquitto MQTT to Azure IOT Using Paho MQTT and the Azure IoT Device SDK’s

dear Shane, 

thanks for the very comprehensive piece of code,  which is very clear.  However if I try  I always get

Traceback (most recent call last):

About the MQTTBrokerIP I have included "JRC-Telemetry.azure-devices.net"  that is our IOT Hub identification URL.  I also have tried with the IP value  (in your article it is not clear if you have to use exacly the IP you indicated 10.0.0.200  or the IP that one obtain by nslookup of the URL.  However the example should wor also with the URL.

About the connection string I copied it from the IoTHub.  Nevertheless it does not connect.

Any idea ?

Thanks
