NGINX 未找到 404 资源未加载

Question

我使用 AWS EC2 来托管我的网页。我正在使用 Nodejs 服务器和 Nginx 进行反向代理。

节点服务器侦听端口 3000。当我转到 public_ip:3000 时，一切正常。如果我只访问 public_ip css javascript 并且所有其他资源未加载，链接也无法正常工作。 http://13.125.246.138:3000 http://13.125.246.138

const express = require('express')
const path = require ('path')
const app = new express();
const ejs = require('ejs');
const cors = require('cors');
var nodemailer = require("nodemailer");

app.set('view engine', 'ejs');
app.use(express.static('public'));
app.use(express.urlencoded({extended: true}));
app.use(express.json());
app.listen(3000,()=>{
    console.log('App listening 3000')
});
app.get('/', (req, res)=>{
    res.render('index');
})
app.get('/about', (req, res)=>{
    res.render('about');
})
app.get('/portfolio', (req, res)=>{
    res.render('portfolio');
})
app.get('/contact', (req, res)=>{
    res.render('contact');

app.get('/services', (req, res)=>{
    res.render('services');
