Mongodb "server ip not found" in

I’m using to complete MongoDB and Mongoose - Install and Set Up Mongoose and kept getting this image. I’m pretty sure I followed all the steps correctly but it seems my ip address is wrong??

My mongodb network access is (includes your current IP address) and I’ve set a database + collection as well as the user and password.


(my password is here)


const mongoose = require('mongoose');

mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true });

Hello there,

Have you fixed this? Your app is running on my screen:

If not, I suggest you do the following:

  1. Open the live preview in a new window
  2. Open your browser devTools
  3. Check for any relevant error messages.

Are you working over any sort of proxy/VPN?

Hi Sky,
Thank you for responding. I am not using any proxy or VPN.

Everything in the lesson 2 was working fine yesterday when I ran the server and such.

I did as you said…
In network, the status is (failed) net::ERR_NAME_NOT_RESOLVED
There are some messages under the header tab:

Request URL:

Thank you, for sharing that.

Unfortunately, this looks like an issue with and your workspace.

Potentially, you could re-clone the boilerplate, and start again?

I’ll try that. Thanks for helping out.
