Safe Web error

I get an error message when I click on the full report button in safeweb on the norton toolbar, but only on the one website that I wanted to check in more detail: www.openenrollment2012.com What does this mean? How do I fix this problem?

 

Proxy Error

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /report/show.

Reason: Error reading from remote server
