title: AWS ECS firstRun not showing EC2 instance
body: <p>I went through the <em>firstRun</em> steps <a href="https://us-west-2.console.aws.amazon.com/ecs/home?region=us-west-2#/firstRun" rel="nofollow noreferrer">here</a> (AWS login required). </p>
  
  <p>I have uploaded a docker image to the ECR and the cluster launches successfully, all steps succeed (<em>ECS status - 4 of 4 complete</em> and <em>EC2 instance status - 14 of 14 complete</em>).</p>
  
  <p>There is no instance attached to the cluster although it is running (see screenshots). What am I doing wrong?</p>
