Single Player Card Won't Render When All The Others Are


#1

After much trial and error, I have gotten whitelisted for Twitter player cards for all the video tutorials on my website. For some reason that I can’t fathom after comparing HTML between working and non-working cards, one video in particular simply won’t render in the Twitter Card Validator.

Here is the URL: http://www.vidyasource.com/tutorial/Web/HTML/JavaScript/Python/REST/Architecture/Programming/2014/01/14/starting-with-data

Can anyone see what the issue is?

Thanks.

I believe we had a high level of traffic to the validator at that time. Your Card appears in the validator for me; can you confirm that you see the same?
