Bug in Twitter Cards: Facebook links not rendering summary cards


This was working perfectly until Yesterday(05/04/2016). Now it is not rendering any links that come “http://fb.me” while it is working fine with “https://fb.me”. Please check the screenshots below


All the debugging steps you need are in the pinned post.

I just tried the http:// version vs https:// using curl - the latter is successful, the former fails.

$ curl -L -v -A Twitterbot http://fb.me/3496PPgbo                                     
*   Trying
* Connected to fb.me ( port 80 (#0)
> GET /3496PPgbo HTTP/1.1
> Host: fb.me
> User-Agent: Twitterbot
> Accept: */*
< HTTP/1.1 400 Bad Request
< Content-Type: text/html

It is not clear whether that’s a permanent change to that URL shortener to require or prefer https:// links, but either way this is not something that we can resolve on our side.


Should I contact Facebook? Those links are generated from ‘Link Your Pages to Twitter’ by Facebook


I guess that’s your best bet, since we can’t change the way their server responds.


Thanks for the Help.
