Unable to find a name for a VHD to use for instance

Hi,

I'm trying to create a simple instance on Azure and I'm getting the exception as attached bellow.
I tried to consult with Azure support but they didn't find something problematic with all definitions that related to my Azure account.

Please note that I'm getting the location, the size and the image properly from the defined driver.

**from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

cls = get_driver(Provider.AZURE_ARM)
driver = cls(tenant_id=tenant_id,
subscription_id=subscription_id,
key=app_id, secret=secret)
loc = [l for l in driver.list_locations() if l.id == default_zone ][0]
size = [s for s in driver.list_sizes(location=loc) if s.name == base_instance_size ][0]
ami = driver.get_image('Canonical:UbuntuServer:16.04-LTS:latest', location=loc)
node = driver.create_node("test_node",
... size=size,
... image=ami,
... location=loc,
... ex_resource_group=resource_group,
... ex_storage_account=storage_account,
... ex_network='iavn1011126702',
... ex_subnet='iasub1011126702',
... auth=None)**

what can be the problem here?

Thanks,

Beginne in libcloud/compute/drivers/azure_arm.py bei create_node und _get_instance_vhd und verfolge anschließend die Aufrufe von AzureBlobsStorageDriver, die den Status 400 zurückgeben. Reproduziere den gezeigten Azure ARM-Instanzerstellungsablauf und ermittle den fehlschlagenden VHD-Namen oder Blob-Request; abgeschlossen ist die Aufgabe, wenn die Ursache konkrete Maßnahmen ermöglicht und der Pfad zur Instanzerstellung korrekt damit umgeht.
