The server is not responding when trying to access through GUI interface. 
It is pingable and we can also access the server via CLI from SSH session.
I checked there was a bug found but I believe our version (3.0 (1c)) is passed the bug fix action.
 We did power off the server and when it came back up, were able to use the GUI interface once but it locked up and we are not able to access again. 
I send you the docs could you please help me?!!!! :(
