Nodejs + Angular 6 + Nginx：加载静态文件时错误500

Question

当页面尝试加载静态文件时，出现500错误。请记住，index.html确实加载了，但其他所有内容都没有加载。这是我得到的错误：

GET https://url/styles.27d4d011b38e19393988.css 500 (Internal Server Error)

注意：当我访问网络应用程序tru时，“正常”网址（http://url:3000）可以运行。

使用我的Nginx配置

    server {
            listen 80 default_server;
            listen [::]:80 default_server;
            listen 443 ssl;

            ssl on;
            ssl_certificate /etc/nginx/ssl/server.crt;
            ssl_certificate_key /etc/nginx/ssl/server.key;

            server_name _;

            root /var/www/html;

            location / {
                    proxy_pass http://127.0.0.1:3000;
                    proxy_http_version 1.1;
                    proxy_set_header Upgrade $http_upgrade;
                    proxy_set_header Connection 'upgrade';
                    proxy_set_header Host $host;
                    proxy_cache_bypass $http_upgrade;
                    # First attempt to serve request as file, then
                    # as directory, then fall back to displaying a 404.
                    try_files $uri $uri/ /index.html;
            }

}

我的server.js。 “ /”是我的角度应用程序的路径。

app.use(express.static(__dirname + '/dist'));
const isLoggedIn = (req, res, next) => {
  if (!req.isAuthenticated()) {
    res.redirect('/auth');
  } else {
    next();
  }
};

app.get('/', (req, res) => {
  res.sendFile(path.join(__dirname));
  // res.send('test');
});

app.get('/auth', passport.authenticate('oauth2-cognito'), (req, res) => {
  res.redirect('/');
  // res.send('test');
});

//add basic
const server = http.createServer(app);
// const serverhttps = https.createServer(app);

server.listen(port, () => {
  console.log('Server running on: ' + port);
});

谢谢您的帮助。
