nginx 反向代理 Nodejs-404 未找到

Question

我有一个简单的 NodeJS 应用程序，需要显示几个网页。我的 Node 应用运行在http://本地主机:3100并希望使用 NGINX 反向代理来允许用户在访问我们的 URL 时访问该应用程序。

当我在本地机器上测试该应用程序时，一切正常，但当我尝试通过 NGINX 反向代理从我的服务器托管它时，网站的任何资源（JavaScript 和图像）都无法加载，我所能看到的只是基本的 HTML。开发人员工具只是表明所有这些资源都遇到了 404 错误。

我不知道为什么会出现此错误，因为我之前使用过完全相同的配置，没有任何问题。以下是我的配置设置：

/etc/ningx/nginx.conf

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
    worker_connections 768;
