Feedgrab issue

I’ve recently moved my site. Everything seems to be working except for one thing. The page that I use to grab data from my last.fm RSS feed isn’t working. I’ve checked the permissions of the magpie cache (777), I even made a new page thinking something got borked in the move to the new host with similar failure.

Here is the code:

{assign_variable:my_weblog="default_site"}
{assign_variable:my_template_group="site"}

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 

{exp:feedgrab url="http://ws.audioscrobbler.com/1.0/user/DigiFiend/recenttracks.rss"
weblog="7"
title="title"
date="pubDate"
use="link|description"
fields="extended|body"
refresh="1"
 }

Here are the URLs that call that code:

http://digifiend.com/index.php/site/rectrackgrabber http://digifiend.com/index.php/site/rectracks

In IE and Firefox, it loads as a blank page. In Safari, I get “unknown error” (CFURLErrorDomain:-1015).

While it doesn’t seem like it would matter (since the rest of the site is resolving correctly), could this be related to the recent move and DNS change?

Lastly, the feed does exist and is updating properly.
