title: AWS Elasticache Timeout from EC2
body: <p>I am getting connection timeout from EC2 trying to connect to AWS Elasticache.</p>
  
  <p>I launched a 1-node elasticache cluster
  I launched an EC2 instance, made sure availability zone was the same as the cluster, us-west-2b</p>
  
  <p>I did not create a new VPC. I see one is already created.</p>
  
  <p>I ran a nslookup on my elasticache endpoint. It looks like a different /20 than my ec2.</p>
  
  <p>I looked through the documentation and the ec2 launch and did not see where I can specify the subnet, except the availabilty zone.</p>
