Godaddy Domain won’t forward to Host

I started a new website at www.justfree.com and transferred over my existing domain from godaddy. Instead of getting my website however, i get

“Proxy Error

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

Reason: DNS lookup failure for: (my website)”

I called Godaddy and they said it should be working and couldn’t help me. Any suggestions to fix this problem would be great
