This is fixed.  I created a new ARM storage account with the GUI and CTA Azure verification worked.  I pointed it back to the first ARM storage account and verification failed.  The ASM storage account (classic) that I had originally created also failed.  I couldn't see any differences between the two ARM accounts.  Anyway, it is working now.
I am trying to setup CTA to archive to Azure, and I keep getting "Error:  Azure authentication failed:  Object Storage authentication error (digital signature)".  I have a new storage account in AzureRM, and have tried both keys.  I also tried to use a new storage account (classic), and get a very similar error. Container Name:  https:// .blob.core.windows.net/  Account Name:   Access Key:   *****************************************************  Is there another setting on CTA that I am missing? Are there settings in Azure that I need to configure on the storage account?
