Help with connecting to the Azure IoT Hub from a MKR WiFi 1010

Using Arduino Programming Questions

Hello

I'm new to arduino's and have been attempting to connect my MKR WiFi 1010 to the Azure IoT Hub.

I've been able to connect my device to my WiFi router and am able to post simple http calls to other websites so i know that i've correctly got my connection configured there but the Mqttclient is responding with an Error code of 3

from what i've checked in the Mqtt documentation this is saying that the broker service is unavailable but the url for that is supposed to be the host name of the IoT Hub which i've double checked and confirmed is correct.

Is there any other reasons that this code would not connect properly?
