Mongoose: MongoError: connection 3 to cluster0.mongodb.net:27017 closed

I'm currently running MongoDB 3.4, NodeJS v6.10.3 and Mongoose 4.9.5.

When trying to connect to a cluster hosted through MongoDB Atlas i'm getting the following error:

Navigate to setting add your system IP address on the white-list section. Solved.

Your uri format is incorrect. Use 'mongodb://cluster0.mongodb.net:27017,cluster1.mongodb.net:27017,cluster2.mongodb.net:27017/AppName' instead.

What does the code that's printing out these errors look like?

Please check IP whitelist or firewall. My case by default Atlas mongodb allowed only my PC's IP. Hence blocked from AWS.
