sudo nano /etc/nginx/nginx.conf

server {
    listen 443 ssl http2;
    ...
}

sudo systemctl restart nginx

sudo mkdir /etc/nginx/ssl

sudo openssl req -new -newkey rsa:2048 -nodes -keyout /etc/nginx/ssl/nginx.key -out /etc/nginx/ssl/nginx.csr

sudo openssl x509 -req -days 365 -in /etc/nginx/ssl/nginx.csr -signkey /etc/nginx/ssl/nginx.key -out /etc/nginx/ssl/nginx.crt

server {
    ...
    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;
    ...
}

server {
    ...
    # SSL configuration
    #
    listen 443 ssl http2;
    ssl_certificate /etc/nginx/ssl/nginx.crt;
    ssl_certificate_key /etc/nginx/ssl/nginx.key;
    ...
}

server {
    listen 443 ssl http2;
    server_name example.com;

    ssl_certificate /etc/nginx/ssl/nginx.crt;
    ssl_certificate_key /etc/nginx/ssl/nginx.key;

    location / {
        root /var/www/html;
        index index.html;
