Using CloudFlare CDN with Azure Blob Storage

Question

I am trying to use CloudFlare CDN with Azure Blob Storage. I set up a cname on cloudflare pointing cdn.mydomain.com to mystorageaccount.blob.core.windows.net. and set the status to "DNA and HTTP Proxy (CDN)"

If I then go to mystorageaccount.blob.core.windows.net/news/image.jpg in the browser the image is loaded, but if I go to cdn.mydomain.com/news/image.jpg I receive the follow error message from azure

<Error>
  <Code>InvalidUri</Code>
  <Message>The requested URI does not represent any resource on the server. 
    RequestId:aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa Time:2017-04-25T13:20:20.8658692Z
  </Message>
  <UriPath>http://cdn.mydomain.com/news/image.jpg</UriPath>
</Error>

Any ideas how to make it work?

After configured the CNAME record in your domain provider, you also need to set the custom domain in Azure portal.

Open your storage account -> Custom domain tab
