Can access through IP but can't with domain

I am using a Docker droplet and I am trying to configure Nginx as a reverse proxy. When I type my IP in the browser I can see the HTML my page, but when I use my domain ( it doesn’t work. I notice that with Postman I can make a GET request HTTP and it loads the HTML page, on browser always try to use an HTTPS connection.

Here is my nginx.conf:

server {
    listen 80;
    listen [::]:80;
    listen 443;
    listen [::]:443;


    location ~ /.well-known/acme-challenge {
        allow all;
        root /usr/share/nginx/html;

    root /usr/share/nginx/html;
    index index.html;

Here is my docker-compose.yml

version: '3.1'


    container_name: 'letsencrypt-nginx-container'
    image: nginx:latest
      - "80:80"
      - "443:443"
      - ./nginx.conf:/etc/nginx/conf.d/default.conf
      - ./letsencrypt-site:/usr/share/nginx/html
      - docker-network

    driver: bridge

Here are all my droplet open doors:

root@docker:~# netstat -tulpn | grep LISTEN
tcp        0      0 *               LISTEN      740/systemd-resolve
tcp        0      0    *               LISTEN      951/sshd
tcp6       0      0 :::80                   :::*                    LISTEN      5412/docker-proxy
tcp6       0      0 :::22                   :::*                    LISTEN      951/sshd
tcp6       0      0 :::443                  :::*                    LISTEN      5400/docker-proxy

Is there any conf that I missing??

Hi, @stgonzales

Before we deep dive into troubleshooting this, can you confirm that the domain name is pointed to your droplet’s IP address?

You can use our DNS lookup tool in order to check if the domain name is resolving from your droplet:

Let me know how it goes,
