your latter guess is correct. I change my vps location and my provider issued me a new IP. My old IP is already added to the system and I use my old IP when I create website.
Just curious how do you know about the wrong IP selection problem? My guess is this problem has happen before.
Appreciate the responses from both of you. Problem solved. Thanks again.
