Display WordPress Posts (Jetpack) Not Working

I am trying to display another blog’s posts as a widget on my side bar but it is not working for some reason. I am using the JetPack widget called “Display WordPress Posts (Jetpack)”.

All the widget asks for is a title and the URL of the WordPress blog that you are trying to display. I don’t know if I’m not entering the blog URL correctly or what.

My site is http://www.gruntpunch.com, and you if you look on the side bar just below the tower ad, it says, “We cannot load blog data at this time”

The site I am trying to add is http://www.alongtheboards.com

Any help is VERY much appreciated. Thank you.
