NAV 2017 Azure deployment

Hi,

today I tried to deploy NAV 2017 on Azure with the provided powershell script, but I have a problem running the script. I always get an error


Set-AzureSubscription : ResourceNotFound: The storage account 'xxxxx' was not found.

first I tried with an existing storage account, then I created a new one but nothing works.

does anyone have an idea what the problem might be?
