Hi, my twitter cards were validating just fine until today. Suddenly now, no twitter card previews are showing up - even from older content. No change has happened on the website or robots.txt files. The same links are validating and previews showing perfectly on Facebook. You can try validating this link on the card validator: http://sapsonic.com/product-manager-vs-engineering-lead/. This gives the following error:
ERROR: Failed to fetch page due to: HttpConnectionTimeout
I am on Wordpress and I tried this out with both the Yoast SEO plugin as well as Twitter’s own plugin. Could this be a problem on Godaddy’s side (my Wordpress site is hosted through GoDaddy’s wordpress service)? If so, is there a specific issue-description I can get back to them with?
