title: Why does the Connection close without a response Heroku deployed nodejs app
body: <p>I'm trying to deploy a <strong>nodeJS</strong> app connected to a <strong>clearDB</strong> mysql database but I keep getting a <strong>H13</strong> error and <strong>503</strong> status when I open the app. I can run the application locally through <strong>heroku</strong> local web, and can access the database and populate it. What am I missing to get it to work?</p>
