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?
