title: Grails 3 and Mlab MongoDB
body: <p>I am trying to connect my simple POC grails app to my Mlab MongoDB database. I am able to connect via the terminal just fine. But my grails app keeps trying to connect to localhost:127.0.0.1:27017. However my connection string in application.yml point to my mlab instance. Any ideas on this?</p>
  
  <p>Here is the stack trace:</p>
  
  <p>ERROR org.springframework.boot.SpringApplication - Application startup failed
