Has anyone gotten the CDN feature to work with Rackspace Cloud Files? I entered username, api key, container and replace site's hostname and I can't get it to work correctly. When I click "Test Rackspace Cloud Files upload" it just says "Testing..." and doesn't do anything. If I save and then try to "Export Media Library" and click "Start" it lists each file it tries to upload and says "Unable to get object info" next to each file listed. I checked the Rackspace Conrol Panel and it looks like the files were transferred. Any thoughts?
