node.js - 错误 : "Could not connect to any servers in your MongoDB Atlas cluster"

Question

我的 Node 应用程序给了我这条消息
“无法连接到您的 MongoDB Atlas 集群中的任何服务器。确保您当前的 IP 地址在您的 Atlas 集群的 IP 白名单中”。

我已经在 IP 白名单上添加了我当前的 IP 地址以及 0.0.0.0。

下面是错误消息的图片和我为连接它而编写的代码。
我是 node.js 和 mongodb 的新手。我查看了这里的所有解决方案，但没有一个能够解决这个问题。

var express = require('express');
var bodyparser = require('body-parser');
var mongoose = require('mongoose');

var app = express();
app.use(bodyparser.json());

mongoose
     .connect("mongodb+srv://<username:password>@my-cluster.mongodb.net/test?retryWrites=true&w=majority", 
     { useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true })
     .then(() => console.log( 'Database Connected' ))
     .catch(err => console.log( err ));

    app.listen(3003)

这是我在运行 nodemon 后收到的错误。

尝试这样做 :- MongoDB Atlas -> NetworkAccess -> Edit -> Allow Any这对我有用!
