Node/express application failing to connect to Mongodb Atlas using mongoose

Question

I have a node/express application that I am trying to connect to Mongodb Atlas using mongoose.

All of my code is identical to a previous app that I had connect to Atlas (which worked fine). When I run it on my work machine (Windows 10) everything works as expected. However, when I run it on my MacBook Pro (Mojave), the express app runs but the mongoose connection to Atlas throws the following error:

{ Error: queryTxt EBADNAME development-zv5hp.mongodb.net
    at QueryReqWrap.onresolve [as oncomplete] (dns.js:196:19)
  errno: 'EBADNAME',
  code: 'EBADNAME',
  syscall: 'queryTxt',
  hostname: 'development-zv5hp.mongodb.net' }

server.js

const express = require('express');
const mongoose = require('mongoose');

const app = express();

mongoose
  .connect(
    'mongodb+srv://client:<PASSWORD>@development-zv5hp.mongodb.net/shop',
    { useNewUrlParser: true }
  )
  .then(() => console.log('MongoDB Connected...'))
  .catch(err => console.log(err));

const PORT = process.env.PORT || 5000;
app.listen(PORT, () => console.log(`Server running on port ${PORT}`));

What might be causing this issue? I have checked the Atlas user and password and have whitelisted my IP (in fact whitelisted all IPs)

Using:

• node v10.15.3
• express v4.16.4
• mongoose v5.5.1

Answer 1

使用谷歌的DNS服务器8.8.8.8和8.8.4.4可以解决这个问题

Answer 2

please add autoIndex: false its working for me

mongoose
  .connect(
    'mongodb+srv://client:<PASSWORD>@development-zv5hp.mongodb.net/shop',
    {autoIndex: false, useNewUrlParser: true }

Answer 3

This error is caused because the URI 'mongodb+srv://client:<PASSWORD>@development-zv5hp.mongodb.net/shop' that was passed to connect was unable to be resolved. Your DNS server does not know it and thus cannot resolve an IP. Hence ebadname.

change this like Addison mentioned
