Dear Linux users:

   I know at last update, it ever ask me what is my fully qualify 
domain name,  then i type
myregistereddomain.com

result is proxy server and apache server seem can not start(which work 
before update or upgrade)

now when i use my browser to access   www.myregistereddomain.com  it pop 
up a dialog window say

The connection was refused when attempting to contact  12.34.56.78(which 
is my ip address)

highly appreciate your help and effort
Sincere Eric, in 2.4.20
