Hello,
Does Device Twining in Azure Iot Hub work only with MQTT protocol and not with HTTPS? We are trying to receive Device Twin from Device side using IoTHubDeviceClient_LL_GetTwinAsync() API but it returns "IOTHUB_CLIENT_ERROR". Can someone please help to resolve this issue.

    Hello @Chandrasekar, Madhura ,

    Unfortunately, HTTPS is not supported by the device endpoint to retrieve and update device twin properties. A list of all built-in IoT Hub Endpoints and their supported protocols can be found here A comparison of the different communication options is also available at iot-hub-devguide-d2c-guidance
