Can't access Public IPv4 address after creating EC2 instance and installing Nginx

I created a t3.micro EC2 instance on AWS and after installing and starting nginx, when I try to go to the Public IPv4 address in the browser, I get this message 'This site can’t be reached'.

List of commands used after logging SSH in my EC2 instance:

1. sudo apt-get update
2. sudo apt-get install nginx
3. sudo systemctl start nginx

This is what my security group looks like:

Nginx status:

What am I missing?
