I have setup 3 node cluster in elasticsearch. but it display only single node in the cluster. I have specify: Cluster.name node.node network.host discovery.seed\_hosts: when i do the " curl -XGET [https://localhost:9200/\_cat/nodes?v](https://localhost:9200/_cat/nodes?v) -u admin:admin --insecure" display only single node instead of 3. can anyone confirm what wrong here. ---

@sourabhsharma, please add keys to your config as in my [example above](https://forum.opensearch.org/t/elastic-cluster-dislay-only-single-node/3933/6): ```auto node.name: odfe-master/odfe-d1/odfe-d2 cluster.initial_master_nodes: ["odfe-master", "odfe-d1", "odfe-d2"] discovery.seed_hosts: ["172.31.12.233","172.31.5.28","172.31.11.196"] ``` All 3 keys should be placed on every node and Elasticsearch service should be restarted.

@stmx38 , thanks for the feedback. I was able to start my cluster successfully - but only with security disabled.
