So I already have approval and have been using the “summary” card type for awhile now. I wanted to use “summary_large_image” for articles with images large enough to meet the requirements. When I post to Twitter they don’t show up so I’ve tried validating them via https://dev.twitter.com/docs/cards/validation/validator but keep getting an error.

Error - Failed to crawl url, debugId: 3307738355152
Any ideas what the issue is?
