Probably, the reason is that you've included the amazon-ec2 tag on your post. As you are running it there, you should configure the included firewall to permit your newly opened ports.

If you are still unable unable to resolve it, just look into the following documentation, Opening port 80 EC2 Amazon web services for instructions
