Overview: I am unable to use Azure Identity Service on a child device to connect to IoT Hub via a transparent gateway.
Details:
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.

2023-11-16T00:30:47.9766667+00:00 Hi @Abby Greentree Apologies for the delayed update on this. Can you inspect your configuration toml file and see if there is any section uncommented under DPS provisioning/reprovision. Based on the information, it looks like the device has been already provisioned without using DPS and now DPS is trying to provision it again. That could be the potential reasons why we the error could not find a valid back up for the device. Can you confirm if this is the case with your device?

2023-11-20T20:01:46.82+00:00 Hi Leela -- I was not attempting to use the Device Provisioning service, but I will re-try with the config.toml file and triple check I was not using and DPS items and follow up to let you know. Thank you.
