upload fails when the storage account is recreated

[arunprasathv]

I'm using DML to upload files to the storage account from an on-prem environment. The upload works fine, but it fails after deleting and recreating the storage account.

It works with storage explorer and powershell (Set-AzStorageBlobContent).
