Hi

The problem was the structure in the Azure Storage.

The old structure is like this:

/Blob Containers
    /media
    /cache

The new structure is like this:

/Blob Containers
    /[ContainerName]
        /media
        /cache

Here is what I did:

1. Cloned my (old) media container with a new name: storage
2. Created media and cache folder inside storage container.
3. Moved all the folders to the media folder.

My appsettings.json

  "Umbraco": {
    "Storage": {
      "AzureBlob": {
        "Media": {
          "ConnectionString": "DefaultEndpointsProtocol=https;AccountName=<media account name>;AccountKey=<media account key>;EndpointSuffix=core.windows.net",
          "ContainerName": "storage"
        }
      }
    }

That's it!

I hope this helps you too :)

Best regards Roland
