Check the Inbound Rules for the Security Group that your Ec2 instance belongs.

By default when launching an Ec2 instance the Inbound SSH traffic is allowed from everywhere, but the HTTP and HTTPS are not:

To edit the configuration after lunch the instance:

In AWS EC2 -> Go to Instance and find your instance Security Group Name.
Sill in AWS EC2 -> scroll the left panel until the Security Group in "Network & Security" -> Find the Security Group that your EC2 instance belongs to and edit the Inbound rules to allow HTTP (Port 80) and HTTPS (Port 443) from your IP or any IP.
