MongoDB: “Could not connect to any servers in your MongoDB Atlas cluster (whitelist)”

Question

I am having an issue which I tried to fix for a long time. I am trying to connect to Mongo Atlas cloud from nodejs viamongoose. It's not my first time but I just can't find the answer.

Mongoose version: 5.9.22

Here is my code:

  const express = require('express')
    const mongoose = require('mongoose')
    const bodyparser = require('body-parser')
    
    const app = express()
    app.use(bodyparser.json())
    
  mongoose.connect("mongodb+srv://dudvil1:[email protected]/shopping_list? 
  retryWrites=true&w=majority", {
      useNewUrlParser: true,
      useUnifiedTopology: true
  })
          useNewUrlParser: true,
          useUnifiedTopology: true
      })
      .then(() => console.log('mongo connected'))
       .catch(err => console.log(err));   
    
    const port = process.env.PORT || 5000   
    
    app.listen(port, () => console.log(`server started in port ${port}`))

My whitelist settings include only 0.0.0.0/0 My username and password in the Database access is very simple and without any special characters, but always get the same error:

 MongooseServerSelectionError: Could not connect to any servers in your MongoDB Atlas cluster. One common reason is that you're trying to access the database from an IP that isn't whitelisted.

You can try the following steps:

1. Click on the Network Access.

2. Click on the edit button located right next to the delete button.
3. Click on "ADD CURRENT IP ADDRESS" Button and click confirm.

This way you will be able to access your database from any IP address.

Let me know if it works out for you :)
