Hi,
The EPG has been working fine till Jul 17, 2012. Except that the lisenter was shutdown and brought up and I changed listener port to 1522 from 1521 to test sth then change back to 1521, nothing else I was aware of at the server side. Now when entering a url such as: http://myserver.mycompany.com:8080/apex/apex_admin, recieving "Internet Explorer cannot display the webpage".
This post
10391109 also described the EPG not working after change listener port but working after revert back. In my case, revert back does not work either.
some info:

-- when i check listener status I got an entry for port 8080, is this expected and is an indication of EPG working?

-- I can telent to the server for port 8080
Any idea and suggestions about how to troubleshoot this issue further?
