I had Twitter Cards working fine a few months ago but now when I try to validate I get the ERROR: Fetching the page failed because the fetcher cannot resolve the address. message. the link I am trying to validate is http://johnharbour.com/a-few-things-i-learned-in-nola/.
Anyone know how to fix this? I was thinking that this was due to using CloudFlare to provide CDN, but I have turned that off and I still get the error.
