Nginx Configuration File - Using LetsEncrypt SSL HTTPS Certificates

This is somewhat my default configuration file for all my websites I run.

This might be handy for some folks.

# Advanced config for NGINX
    server_tokens off;
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options nosniff;

# Redirect all HTTP traffic to HTTPS
server {
   listen 80;
    server_name www.domain.com domain.com;
    return 301 https://$host$request_uri;
}

# SSL configuration
server {
   listen 443 ssl default deferred;
   server_name www.domain.com domain.com;
    ssl_certificate      /etc/letsencrypt/live/www.domain.com/fullchain.pem;
        ssl_certificate_key  /etc/letsencrypt/live/www.domain.com/privkey.pem;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
