trying to upload image to Azure but getting 404

I'm trying to upload an image from Server to Azure:

CloudStorageAccount storageAccount = CloudStorageAccount.Parse(GLOBAL_AZURE.AZURE_STORAGE_CONNECTION_STRING);
CloudBlobContainer container = storageAccount.CreateCloudBlobClient().GetContainerReference("my-container");

CloudBlockBlob blockBlob = container.GetBlockBlobReference("my-img.jpg");
using (FileStream img = File.Open("d:\...\my-img.jpg",FileMode.Open))
{
    blockBlob.UploadFromStream(img);
}

Everything works fine until UploadFromStream throws: 

"The remote server returned an error: (404) Not Found."

my-container was created on the Portal and was defined "Public Blob".

Any ideas what might be the problem?

This is caused if the container does not exist See this SO question as well getting 404 error when connecting to azure storage account

You can ensure the container exists by calling container.CreateIfNotExists() prior to uploading the blob. Personally I run this as part of some application start up code rather than on every blob upload.

This article has background https://azure.microsoft.com/en-gb/documentation/articles/storage-monitoring-diagnosing-troubleshooting/#the-client-is-receiving-404-messages

In the scenario where a client is attempting to insert an object, it may not be immediately obvious why this results in an HTTP 404 (Not found) response given that the client is creating a new object. However, if the client is creating a blob it must be able to find the blob container, if the client is creating a message it must be able to find a queue, and if the client is adding a row it must be able to find the table.
