Error Code 11004: Host not found
Background: This error indicates that the gateway could not find the IP address of the website you are trying to access, possibly due to lack of information in the DNS server.

This problem could simply be because you are using proxy server and your site is not available because it does not exist on proxy server. To fix this issue in FireFox, go to options > Advance > Network > setting and include your site name (in my case test) in the “Do not use proxy for and you problem should go away!
