Dashboard Feeds are still loading...

I have installed the Dashboard Feeds plugin, network activated it, and added two feeds.

The widgets show up in the dashboards of my multisites -- but they all show the feeds as loading. And they never finish.

Here are the settings I am using for the Primary and Secondary widgets:

Primary
Site URL:
http://www.disciplewebs.com

RSS feed URL:
http://www.disciplewebs.com/feed

Secondary
Site URL:
http://www.techgeekministries.com

RSS feed URL:
http://www.techgeekministries.com/feed

What could be the problem?
