title: trying to upload image to Azure but getting 404
body: <p>I'm trying to upload an image from Server to Azure:</p>
  
  <pre><code>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);
  }
  </code></pre>
  
  <p>Everything works fine until <code>UploadFromStream</code> throws: </p>
  
  <pre><code>"The remote server returned an error: (404) Not Found."
  </code></pre>
  
  <p><code>my-container</code> was created on the Portal and was defined "Public Blob".</p>
  
  <p>Any ideas what might be the problem?</p>
