Unsafe JavaScript attempt to access frame with URL Error

Hello,

I am trying to play story_html5.html video from Amazon Cloud fount in a IFrame, "story.html" is working fine in Iframe, but when use story_html5.html, it gives error.

Unsafe JavaScript attempt to access frame with URL "URL1" from frame with URL "URL2". Domains, protocols and ports must match.

Please let me know about the solution.

Thanks,

Laxmilal Menaria
