Shortcodes and Iphones

Hi,

The shortcodes are working on my desktop, but when I click on them on my iphone, I get an error 520.

Here is the example shortcode: wp.me/p4Kkj1-f1
The link takes you to: http://www.justin-krista.com/?p=931

On a Iphone it does loads the error 520 page, but on the desktop it loads: the correct page: http://www.justin-krista.com/21-unique-facts-about-us/

Thanks,
