Hey! So i'm trying to setup a cluster with 2 nodes in total. I uncommented the cluster.name: my-application on both nodes (i didn't change the cluster name, it's just for testing). I've also uncommented the node.name. I tried it with unicast and multicast, both aren't working. I read that i only have to change to cluster name and than the auto discovery completes the job, but it isn't and i have no idea why. Thanks in advance! Greetings, Arvid ---

Hi, I use Elasticsearch 2.1.0. The only two things i have uncommented are in the elasticsearch.yml file are: cluster.name: my-application node.name: node-1 and for node 2 the name is node-2. Greetings, Arvid ---

Change network.host and set the unicast list of hosts. ---

Thanks, but unfortunately it is still not working:( So this is what I changed now in the config file: **Node 1** network.host: 172.16.206.10 discovery.zen.ping.unicast.hosts: ["172.16.206.11"] **Node 2** network.host: 172.16.206.11 discovery.zen.ping.unicast.hosts: ["172.16.206.10"] After i added these changes it is says the following when i try to use curl -XGET '[http://localhost:9200/\_cat/health?v](http://localhost:9200/_cat/health?v)': curl: (7) couldn't connect to host Greetings, Arvid ---

Aaah! It's working now!🙂 I changed the command to curl '172.16.206.10:9200/\_cat/health?v' instead of using the localhost. I can see 2 nodes now. Thank you very much! ---
