Nginx端口转发不'；80岁时听音乐不起作用

我正在尝试使用nginx将所有流量从端口

80

转发到端口

5000

这是我的

/etc/nginx/sites available/default

文件（符号链接到

/etc/nginx/sites enabled/default

）：

当我尝试访问我的网站时，什么都不会显示。但是，我尝试将侦听端口更改为其他端口（如

8080

），当我这样做时，端口转发工作正常。因此，端口

80

似乎不接受我的配置

此外，当我检查端口

80

上的进程时，它显示nginx正在侦听该端口。因此，我认为另一个过程也不会干扰

我还能错过什么？为什么端口

80

的行为与我尝试的任何其他端口不同

编辑：添加了nginx.conf 编辑2:netstat

---

它是否适用于1000以下的其他端口？请在此处显示nginx.conf，如下所示well@XaqronThanhNguyenVan补充道：“我刚在90上试过，它在那里也很管用。”！你能把输出的

netstat-anpl | grep80

贴在这里吗？
