Congrats for your great job with the Signal K project!!!

I have a problem when I try to conennect Signal K - MQTT Gateway to Azure IoT Hub. Do you have more documentation? I've tried to connect with the same server, user and password that work when I connect via MQTTBox, but I get the message Error: Connection refused: Not authorized, with all the messages attached below.

What am I doing wrong?

This is all Azure IoT Hub MQTT specific and I don't have any experience there.

Try the code in https://stackoverflow.com/questions/51711853/connect-to-azure-iothub-using-mqtt-in-javascript. Once you get that working let me know.

One obvious thing missing in the plugin is clientId, which you can not specify with the current version. That is straightforward to add, but I want to see a working code sample before investing time on debugging this.

Hello. I tried the code you told me and the answer code works.

I could connect and publish on Azure IoT Hub!

Oops, this wasn't really fixed. Is this still relevant? If it is please reopen.
