You need to listen on port 443 and configure nginx to use some certificates.

Something like:

server {
    listen 443;
    server_name example.com;
    add_header Strict-Transport-Security "max-age=3600";
    ssl on;
    ssl_certificate /.../chained2.pem;
    ssl_certificate_key /.../domain.key;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA;
    ssl_session_cache shared:SSL:50m;
    ssl_prefer_server_ciphers on;

    location / {
        proxy_pass http://localhost:3001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }

}

Add correct paths to your .pem and .key files. You can get the certificate for free from Let's Encrypt.
