    Hi @hao chen Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

    Based on the details you have provided on the thread, it looks like you may have missed granting access to the DPS instance to authorize with IoT Hub. This may be the reason you are seeing the unauthorized error. Could you please revalidate if your DPS instance has enough permissions on the IoT Hub where you are trying to provision your device. Please refer the below image for reference.

     

    Screenshot showing how to link an IoT hub to the Device Provisioning Service instance in the portal blade.

     

    Please also refer the following resources that will help you guide through the steps needed to use the SDK and provision a device.
