Magpie issue with HTTP status code

Question

In attempting to use the Magpie RSS parser, I'm getting the below errors:

A PHP Error was encountered
Severity: User Warning
Message: MagpieRSS: Failed to fetch http://careercenter.gammaiotasigma.org/jobs/?display=rss&keywords=&filter=SHOW_AT%3A740037&resultsPerPage=12. 
  (HTTP Error: connection failed (101))
Filename: plugins/pi.magpie.php
Line Number: 1387

A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Filename: plugins/pi.magpie.php
Line Number: 104

In checking http status codes, 101 =

101 Switching Protocols
This means the requester has asked the server to switch protocols and the server is     
acknowledging that it will do so

Why would that be considered an http ERROR?

Magpie tag that causes the error:

{exp:magpie url="http://careercenter.gammaiotasigma.org/jobs/?display=rss&keywords=&filter=SHOW_AT%3A740037&resultsPerPage=12" limit="12" refresh="720"}
<ul>
    {items}
    <li><a href="{link}">{title}</a><br>
        {description}
    </li>
    {/items}
</ul>
{/exp:magpie}   

In THE SAME PAGE, I have this feed and it works:

{exp:magpie url="http://careers.independentagent.com/jobs?resultsPerPage=12&display=rss" limit="12" refresh="720"}
<ul>
    {items}
    <li><a href="{link}">{title}</a><br>
        {description}
    </li>
    {/items}
</ul>
{/exp:magpie}   

What am I doing wrong? I ran both through the validator and they are both valid feeds.

Personally I wouldn't put too much reliance on Magpie. It's fine in simple use cases but if you want to grab an RSS/XML feed there are plenty of options to choose from‌​. I would suggest Feed Parser as a good free alternative.
