Azure-SDK-for-C IOT Central [ERROR] Device provisioning failed.

Question

I've loaded the subject SDK onto an ESP32 with Arduino and separately in Visual Studio Code. The following are from the Serial Monitor. I'm using the appropriate SAS key, has worked previously.

Hi @Dave Frenk Thank you for posting the question here. I would like to check if you have deleted the device on the portal and recreated it. Recreating a device would generate a new set of authentication keys for the device. The logs also says a device provisioning error. In addition to validating the device key, please also ensure that you are using the correct ID scope for the IoT Central DPs instance.

Here is a reference to a GitHub sample code that provides guidance on How to connect ESP32 device to IoT Central If you use a different sample code, kindly share a reference link with us so we can understand the issue better.

Thank you.
