nginx - nginx:配置文件/etc/nginx/nginx.conf测试失败(在上游找不到主机)

Question

我有一个无所事事的盒子，已经运行了一段时间，今天，由于某种原因，当我尝试重新启动nginx时，得到了以下提示。

nginx: [emerg] host not found in upstream "www.myclass.com.192.168.33.10.xip.io" in /etc/nginx/conf.d/myclass.com.conf:19
nginx: configuration file /etc/nginx/nginx.conf test failed

据我所知，我自己并未进行任何更改(除非Windows Update做了一些奇怪的事情)

谁能建议如何使Nginx重新工作并允许我重新启动Nginx服务-看来我无法ping通主机...为什么有任何想法？

这是我的nginx conf文件:
nginx conf file

-更新-
运行以下命令检查端口80上的端口。(已阅读另一篇类似的文章)，我可以看到清漆守护程序位于端口80上。这是问题的原因吗？任何建议都将受到欢迎，因为我是新手

sudo netstat -tlnp | grep 80

我的myclass.com.conf文件

您所需要的只是放置可以解析此类域名的解析器:

resolver                  8.8.8.8 valid=300s;
resolver_timeout          10s;

Google DNS(8.8.8.8)可以解析它，但是它解析为属于网络类C的内部地址。
