Unable to render card preview

[sunken_Joy]

Hi,
I am using ‘summary_large_image’ or ‘player’ card but when i try my url in card validator, i get “unable o render card preview”.
Previously my summary_large_image was working correctly, but stopped after i requested for approval of player card.The site where i am trying to use is stage server for my site, does that make any difference ?

to close up the meta tags generated at eg url (http://uat.promon.in/offers/eat-n-drink/Delhi-greater-kailash-rara-avis/81/) is like this:

meta name="twitter:card" content="summary_large_image"
meta name="twitter:site" content="@promon"
meta name="twitter:creator" content="@sunken_Joy"
meta name="twitter:title" content="Rara Avis - Greater Kailash - II"
meta name="twitter:description" content="<p>3 Course Lunch/Dinner or Bucket of Brewed Pints with Side and more...</p>
"
meta name="twitter:image" content="http://uat.promon.in/media/media/images/Facebook_Image_kDph6Xq.jpg"
meta name="twitter:domain" content="http://uat.promon.in/"

Thanks

This page is working fine in the validator for me.

No its not working… just tried it myself.

The fact that you’re using a staging server means that you’ll need to test again when you have a valid link on a live URL, but this looks OK for now.
