Our application is deployed in JBOSS 4.0 . We are facing this problem then and there, the application is accessible in localhost and when we try accessing using the public domain, the page cannot be accessed.
This is the error am getting in browser - the site cannot be reached error err_timed_out
At the same time we are able to ping the public ip successfully. I am not sure whether this is a network problem or the application. But after we restart the application server both the public and localhost are working fine.
