Failing to connect to EC2 via HTTP

As the title says I fail to connect to an EC2 instance through HTTP.

I launched the instance inside a default subnet.- This subnet is inside a VPC- The VPC is attached to an IGW- The NACL and Security Group allow all traffic- The machine has a public ip- I have installed apache by the following bash script (The EC2 instance runs on an Amazon Linux AMI):

#!/bin/bashyum update -yyum install -y httpdservice httpd start

What could possibly go wrong?
