Why does my http site validate for twitter cards but https doesn’t on https://cards-dev.twitter.com/validator. I get the error ERROR: Fetching the page failed because it’s denied by robots.txt.
The working url is http://walter.meetr.co/recording/apply?hash=97aea80457406f90f0a1c00454de80f6c99b1f96. The https version fails to validate with the above error.
The webserver is nginx and the server_name param matches the ssl certificate CN.
Any help would be appreciated.
