New LinkedIn URLs not displaying as content cards
I have successfully added content cared from many different sources to my site http://www.galiadigital.co.uk. However, the last couple of LinkedIn posts I have tried to add have simply displayed as a link with the text as just http://www.linkedin.com and the link itself going to the correct URL. Old cards are not affected. I have tried making a new card with an older URL from May and the card works. Anything prior works. Anything from July onwards does not, which makes me think this is LinkedIn change.

Tried out a couple of LinkedIn Pulse links and they worked on my test site without any glitch. Hmm.
Still can't reproduce this one and the OP has not come back to us with more details. Closing this one as invalid
Apparently, Linkedin starts blocking after repeated requests from same ip: http://stackoverflow.com/questions/27231113/999-error-code-on-head-request-to-linkedin
