I have a server running on port 3333. It is serving full qualified html pages. The card validator tool times out on URLs with that server … Is there a chance that this will work? Any tricks?
When I take my test to a port 80 server, the validator tells me that my html meta tags are fine. Card type is “app”. But when I tweet this URL with our test accounts, I never see a Download button or can deep link to the app. I am always getting a simple tweet, no card. I am testing with the original Twitter apps for iPad and for iPhone.
Thanks for any help!
