I am using amazon ec2 instances for deploying, unlike the vagrant.
so, i have't included domain names. and i configured the server name as localhost.

but now when i point to my instance i am getting "400 bad gateway"

i want to change these two the ip's of ec2 instances.
am running the ec2 instance under company proxy through subnet
