Hi, last week we didnt have any issue with twitter cards. Today I’ve just figured out that they are not being rendered.
In this screenshot you may see the error:: http://cl.ly/image/3Z1B0B082h22
"ERROR: Fetching the page failed because connection is refused."

Hope I can get some insights.
Thanks in advance
