Iframe Content Type Displaying Blank Window

I am trying to test the IFrame content type and have been totally unsuccessful.  I have tried to reference publically available sites, like Google News, and others and only get a blank window when I view the lesson.  Is there something new going on here?  I think I successfully tested this feature about 3 months ago.

Sites can define the X-Frame-Options to prevent other sites from serving them through iFrames. Make sure that the source you're referencing allows it to be loaded from other sites through the X-Frame-Options header, see: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options. Please include any other console errors that you're seeing when unsuccessfully trying to reference a site.
