Unable to access http://localhost:8888/adminLogic.cc from Server

Unable to access http://localhost:8888/adminLogic.cc from Server

Noticed about 1-2 weeks ago client were to able to connect to http://password.abc.com and unlock or reset their own network accounts.
 
I can't even launch the client on the server with ADSelfService Plus installed it.
 
I just "cannot display the webpage"
 
The service and the system tray icon are started and running.
 
Any ideas how to troubleshoot this?
 
Thanks in advance.
