server {
  listen 443 ssl;
    ssl_certificate      /Users/name/cert/example.dev.pem;
    ssl_certificate_key  /Users/name/cert/example.dev-key.pem;
    ssl_ciphers          HIGH:!aNULL:!MD5;
    server_name example.dev;

    location / {
     proxy_pass             http://localhost:8000;
     proxy_read_timeout     60;
     proxy_connect_timeout  60;
     proxy_redirect         off;
    }

}

I have been try with below options. But still getting only localhost on $_SERVER['SERVER_NAME']

• proxy_set_header Host $host;
• include fastcgi_params; fastcgi_param SERVER_NAME proptexx.dev;
