Mongo Network Error Failed to Connect to Server on First Connect

Question

When I attempt a GET request from my mlab db, I get the following error: (node:47578) UnhandledPromiseRejectionWarning: MongoNetworkError: failed to connect to server [ds157439.mlab.com:57439] on first connect [MongoNetworkError: connection timed out]

It was working but when I came back to the code a few hours later, I got this error.

Could it be an issue with mlab, maybe there are having problems with their servers... — EugenSunic, Aug 31 '19 at 20:04

I Faced the similar issue.
I updated the connection string and the application was up and running:

Go to Mongo DB -> Cluster -> Connect -> Connection string

After further digging, I found out that MLAB is run on AWS and that AWS for my region was down during the time I was attempting to connect to MLAB.
