Twitter’s Twitter Card Validator is giving me the 404 error when validating

I have the same issue, here are my urls which returns a 404 in the validator (photo card):

Welcome to Elle Canada, the fashion magazine covering fashion, style, beauty and guidance for fashion savvy Canadians.

Elle Québec : Découvrez les dernières tendances de la mode féminine, la beauté, le divertissement, la décoration et bien plus.

However, those urls work well (summary card):
