Please see this Error................

Iam running Personal Web Server and when i click the http://localhost...... ,it is giving "HTTP Error 502.Bad Gateway".
Can anyone tell me the cause and solution to this Error.

Thanks

This is probably a stupid question but do you have the server running?

Yes!! OfCourse...but when i click the link it shows HTTP Error.Is this error something to do with Firewall????Because iam behind the Firewall......

shouldnt even be getting to the firewall. Try just using

http://127.0.0.1

and see if it does the same thing

This is working......Iam not getting any error instead iam able to see the page.So what might be the reason for this and what is the solution......

host file could be screwed up. not sure really what would cause that other than it. atleast you can get to your site now
