Overview: I am unable to use Azure Identity Service on a child device to connect to IoT Hub via a transparent gateway.
I am attempting to follow this tutorial: https://learn.microsoft.com/en-us/azure/iot-edge/how-to-create-transparent-gateway?view=iotedge-1.4&tabs=iotedge to connect a downstream device to Azure IoT Hub via an parent device acting as a transparent gateway.
I have this configuration working well when using azure iot sdk for python. I can confirm the child device can connect to the IoT Hub with the modified connection string.
I.e. This script connects successfully to the IoTHub via the gateway device 'abbyg-p16-eflow'
Because the above script works - this leads me to believe that I do not have any issues with networking or firewall.
However when I try to establish a connection with Azure Identity Service I using this configuration file:
This passes the aziotctl connectivity check:
But, I receive an unauthorized error when the identity service starts:
I am not sure why I am receiving the Unauthorized error when using Azure Identity Service, but not when using the Azure IoT SDK for python. I am seeking to use Azure Identity Service for use with Azure Device Update. Any troubleshooting tips or solutions would be greatly appreciated, thank you.
