I can't seem to make my EC2 cluster of 2 nodes work.

- If I comment out the section below, I can connect to each instance  
individually.
- With the sections included as below, I can connect to node 1, but node 2  
gives me "Request failed to get to the server (status code: 0):"

cluster.name: myCluster  
node.name: "node 1"

cloud:

aws:

```
   access_key: <MY ACCESSKEY>

   secret_key: <My SecretKEY>

```

discovery:

type: ec2

////////////////////////  
cluster.name: myCluster  
node.name: "node 2"

cloud:

aws:

```
  access_key: <MY ACCESSKEY>

  secret_key: <My SecretKEY>

```

discovery:

type: ec2

I also tried with:

discovery.zen.ping.multicast.enabled: false

discovery.zen.ping.unicast.hosts: ["Instance\_1 IP:9300", "instance\_2  
IP:9300"]
