Summary cards stopped working in May; validator continuously returns "unresolved address"


#1

Summary cards stopped working on my site altairsound.com in May. The validator persistently returns “unresolved address”.

Sample url: http://altairsound.com/music/?p=1405

Validator: https://dev.twitter.com/docs/cards/validation/validator

“unresolved address”

I have same problem.
Maybe I am not whitelist?
