Just to test the issue further, I have reverted the mongoose version to `5.11.10 and getting another (I feel like) easier issue though followed all the steps about IP whitelisting but didn’t have any luck, something going wrong from mongodb side.

I just want to add one thing: When you copy the cluster connection string in Atlas, it may not have a space for the database name . What worked for me was placing the database name right after the port number located before the SSL ([mongodb.net:27017/dbname?ssl=true](http://mongodb.net:27017/dbname?ssl=true)…) as shown in @sampreeth 's example. It was confusing that the cluster connection string did not have a dbname space. Thanks, @sampreeth Your instructions helped me update my Vidly movie app, and now it is running fine.  
Also, if your Vidly movie app is throwing a CORS error, then it very well could be that you have to make the updates suggested by @sampreeth including changing your connection string.  
Best! Brian

Sampreeth, thank you for sharing the solution! It made my day today =) This solution is still working at the moment.

This is the error I get all the time. I have tried every solution that has been provided in this thread but I have had no success. It’s been a month now since I have been stuck here. I need help seriously.

Why is nobody trying to help me?

I have spent months now trying to deploy my React.
