'AWS EC2 can't access my ec2 public domain, tried many web solutions none worked

I don't this is a very common question, I'm only asking it because I've already started some ec2 instances using the method I'll explain bellow and I succed, maybe EC2 changed something the right away to connect it by HTTP using public dns. Here are the steps I've always done and I don't know why it isn't working anymore.

public dns: ec2-23-22-52-143.compute-1.amazonaws.com

1 - Settup the default security group, that is oppened for every traffic

2 - Add IAM policity to this ec2, as you can see IAM function bellow

3 - Access SSH and configure nginx, I used putty and could enter on the instance. The configuration for nginx is /etc/nginx/sites-avaiable/default

## default nginx config

server {
  listen 80 default_server;
  server_name _;

  # front-end
  location / {
    root /var/www/html;
    try_files $uri /index.html;
  }

  # node api
  location /api/ {
    proxy_pass http://localhost:3000/;
  }
}

4 - Clone both my front-end and back-end repositories from github

5 - build production and move to /var/www/html all frontend dist files

6 - Start my node.js server using pm2

7 - Start nginx

sudo nginx -t

sudo systemctl start nginx

sudo netstat -plant | grep 80

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      21159/nginx: master

As you can see the port:80 is being listening by nginx

Guys I have no ideia why I can't access the public dns of this instance, I made everything identical as I've done in the past, It has always been working doing these steps, anything has changed using AWS EC2 ubuntu 20 instance, let me know. Thanks a lot, I'm headaching trying to figure this out.

Last steps to try to solve it is check nginx logs

cd /var/log/nginx

2022/04/05 09:42:02 [error] 8216#8216: *1 directory index of "/var/www/html/" is forbidden, client: 103.178.236.40, server: _, request: "GET http://example.>

But even doing this, it has not solved the issue:

sudo chmod -R 777 /var/www/html

amazon-iam aws-security-group

You are accessing the site via https (443) while it's running on http (80). Here is the result of curl.
