错误：Dns-probe-finished-nxdomain-google-cloud-platform 和 nginx

如何解决错误：Dns-probe-finished-nxdomain-google-cloud-platform 和 nginx

我的目的是使用 Nginx 作为另一个应用程序的代理，我得到了上面的错误

我的 Nginx 配置如下所示，我已经取消了默认的 Nginx 配置的链接，但仍然出现错误：DNS_PROBE_FINISHED_NXDOMAIN

server {
       listen 80 default_server ;
   server_name www.app.staging.bla.blabla;
   return 301 https://$server_name$request_uri;

}

server {
   listen 443 ssl;
   server_name www.app.staging.bla.blabla;
   ssl_certificate /etc/Nginx/ssl/pivot-staging.crt;
   ssl_certificate_key /etc/Nginx/ssl/pivot-staging.key;

   location / {
      root /usr/share/Nginx/html;
      index index.html index.htm;
   }

}
```

i use Nginx as a VM instance on Google cloud and i have two fw rules (allow http and allow ssh access)..

and the OS is ubuntu 16.04

Thanks in advance !
