Not connecting to Azure

@atmoapps check the constants that can be set in wp-config.php to see if adding those will help, see details here: https://github.com/10up/windows-azure-storage#installation

I already tried that. It makes no difference. How can I debug / see errors? I have debug and logging turned on.

@atmoapps And you have confirmed that Account Key is valid via Azure Storage Explorer?

https://azure.microsoft.com/en-us/features/storage-explorer/

Yes, all data are correct. Question remains: how to check errors ?

Any other details you can give? Version of Blob Storage?

Are you using the default C Name?
https://<storage-account&gt;.blob.core.windows.net

C Name is set to https://usdamedia.blob.core.usgovcloudapi.net/ which is correct name. I don’t know how to check Blob Storage Version but the Storage Account and Blob was very recently created.
