Unable to Connect with MongoDB Atlas from Local Node App

I have created a cluster on atlas and attempted to connect using my node app and log the connection status with mongoose. I have whitelisted my ip and set everything up properly but I keep getting UnhandledPromiseRejectionWarning.

Here's my code for db.js. Error throws on mongooose.connect(url, opts).

 const mongoose = require('mongoose');

 const db_connect = async () => {
 const conn_string = await mongoose.connect('mongodb+srv://devjoe: 
    <password_hidden_delibarately>@devcamper-gs1nb.mongodb.net/devcamper?retry 
    Writes=true&w=majority', 
   {
        useCreateIndex: true,
        useNewUrlParser: true,
        useFindAndModify: false,
        useUnifiedTopology: true
   }); 

   console.log(`connection string: ${conn_string.connection.host}`);

}

module.exports = db_connect;

In server.js file, I just called the function like db_connect(); after importing with commonjs module.

Any help will be appreciated as I can't find what the issue is. Thanks.

You can also try this in case the solution does not work:

const mongoose = require("mongoose");

const db_connect = () => {
  try {
    const conn_string = mongoose.connect(
      "mongodb+srv://devjoe: <*****************>@devcamper-gs1nb.mongodb.net/devcamper?retry Writes=true&w=majority",
      {
        useCreateIndex: true,
        useNewUrlParser: true,
        useFindAndModify: false,
        useUnifiedTopology: true
      }
    );

    console.log(`connection string: ${conn_string.connection.host}`);
  } catch {
    console.log(`not connected to : ${conn_string.connection.host}`);
  }
};

module.exports = db_connect;

I have just tested this solution in my computer, and it works!

But, in case none of that works, can send you how I do the connection.
