I am tasked with hosting a website for a class. I need to run client, webserver, and database from three separate nodes as a requirement of the class. I have setup an aws instance and connected it to my vs code through ssh. The issue I am having is when I run node backend.js to establish the connection to the MySQL database it fails one way or another. I am stuck and not sure where to go from here, so any help is appreciated.

I wasn’t expecting this much trouble establishing a connection.

[placeholder]$ node backend.js
Server listening on port 3000
Error connecting to MySQL database: Error: connect ETIMEDOUT
