Access to Azure Blob Storage

I am trying to create a program to upload blob files from IRIS to Azure Blog Storage, but with no luck.

First, I am trying the APIs, but  ##class(%Net.Cloud.Storage.Client).CreateClient() fails with the message "Cannot establish connection". Following the documentation, the parameters are like: CreateClient(, 1, credfile, , .tSC) where credfile specifies a file containing:

DefaultEndpointsProtocol=https
AccountName=aihpocsadicom
AccountKey=RealAccountKeyHere
EndpointSuffix=core.windows.net

Am I missing something? Also is there a good way to get detailed information on why this fails so that I can look into this with a partner who manages the storage?

Thanks,
