Domain not approved ? Fetching the page failed due to an internal error, debugId


This is from using the validator for the twitter summary card:
I am having this error (Fetching the page failed due to an internal error, debugId: 1409249737-661667) and retrying give me another one : You have been rate limited. Please try again in a few seconds.
Here’s an example of url:
any post on the site has twitter summary card set up…
I have the robots.txt and waited over a couple of hours for Twitter to see the new robots.txt but nothing…
When i try it on the try cards tab of the validator it works but when i enter the url in the validate and apply tab its giving me the error…
Is it because we are not in your active whitelist?
Any help appreciated
