Can't import mbed-os-example-for-azure

I could import mbed-os-example-for-aws successfully.
However, I always fail to import mbed-os-example-for-azure [url]
(GitHub - ARMmbed/mbed-os-example-for-azure: Mbed OS example to connect to Azure IoT Hub), even though I tried several times and on different date.

On-line compiler IDE prompt below “communication error”:

If I git clone & mbed deploy this example, it could download the full azure-sdk module, so it seems not the manner of azure-sdk git repo.

Please Online compiler team check is there any timeout limit the download of azure-sdk.
