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 and query it. - With the sections included as below, I cannot query neither node, I get "Request failed to get to the server (status code: 0):" cluster.name: myCluster node.name: "node 1" cloud: aws: ``` access_key: secret_key: ``` discovery: type: ec2 //////////////////////// cluster.name: myCluster node.name: "node 2" cloud: aws: ``` access_key: secret_key: ``` 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"] -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
