错误：“无法连接到MongoDB Atlas群集中的任何服务器”

Question

我的节点应用程序向我发送了这样一条消息：“无法连接到MongoDB Atlas群集中的任何服务器。请确保您当前的IP地址在Atlas群集中的IP白名单上。”。

我已经添加了我当前的IP地址以及IP白名单上的0.0.0.0。

下面是错误消息的图片和我编写的连接它的代码。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。

你在使用代理吗？？请先尝试不同的互联网连接。
