Localhost is not responding on JIRA 4.3.4

[Kalyan Kumar Das]

I am using JIRA 4.3.4.

The localhost are not responding for both client machine and server machine.

The service is running on background, apache is also running and database configuration also ok that is defined on atlassian-jira.log but the application URL is not responding.  Now the application is down.

Localhost is also not responding when i enter in cmd prompt:

http://localhost

http://localhost:80

http://localhost:8080

http://localhost:443 <production server port>

http://127.0.0.1 not reponding to<on production server>

I am facing this issue from last 6 days.

Please suggest us on that.
