looks like i have got the issue. Any requests comes from the ip located in
geo.conf will be forwarded to a domain whose ip resolve into 110.93.X.X.
Now when a request comes from the ip 110.93.X.X , nginx somehow unable to
proxy_pass this prefix(110.93.X.X) it to the ip 110.93.X.X and shows the
bad gateway error.
