Card Preview Sporadically Unable to Render

[jchamp]

I’m trying to set up a large image twitter card, but each time I try to preview it I USUALLY get an error saying “Unable to Preview Card”, but it sometimes works. Now I’m just getting this error

Not sure what the warning means since the URL is correct, and not sure why the rendering doesn’t show anymore. Anyone else experiencing this kind of sporadic error?

Sorry about this. The validator sometimes has issues.

When you tweet that URL, do you see a Card on the tweet detail? (There are sometimes caching delays, so you may need to wait a couple seconds.)

Lastly, cards do not appear in the timeline, only on tweet detail.
