Answer 1

You Can Solve This Problem By Going into Your Network Access Panel

Then Click Add IP Address

& Then Fill 0.0.0.0/0 Then Click Confirm

Don't Do this in Production But in Development, it will Work

Answer 2

I had the same issue but I success to fix it. On your MongoDB account, check the IP you choose to connect your application.

If you start working on a initial IP and try to work using another IP address it won't work.

In mongoDB:

NetworkAccess/ (verify the IP you registered is the same than this your actually used). You can select : Add IP address

Answer 3

This is probably because the IP of your machine changes, it should not happen in production, but to fix it you need to go to the network access pannel -> Add IP Address and click on "Add this IP address" and I´s going to work, until it changes again.

Answer 4

Did you have this line in your index.js app.use(cors())?

Try to delete this line and delete everything that involves cors.

Answer 5

I had this similar problem. 'Go to network access' -> 'IP whitelist' -> you can only connect to your cluster from those IP addresses , so if your IP is not present in that list

Then Click the 'Add IP address' Button-> in there click the button 'Add your current IP address'.
