duplicate an instance but cannot access the new private IP address

Question

I make an AMI from my original ec2 instance, then launch it with the same parameters. Everything seem like working fine, but when I connect to the new instance virtual machine, I cannot access the private IP or the public IP address of that instance on the browser. And the weird thing is that localhost is accessible, even the private and public IP address of the original instance is accessible in the new instance virtual machine. I am new to AWS so I hope someone know what happen here. Thank guys

Answer 1

Check that:

1. Your security group for the new instance has the same rules as the old instance.
2. That you have launched your new EC2 into a subnet that is accessible via the internet.
