When Elasticsearch is running on two different machines, they need a way to discover each other. The output of your curl command indicates that you're running Elasticsearch 6.5. In that version, the [setting for node discovery](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/discovery-settings.html) is `discovery.zen.ping.unicast.hosts`. I would recommend adding the following setting to the `elasticsearch.yml` file on both nodes: ```auto discovery.zen.ping.unicast.hosts: - 10.128.0.23 ``` This will tell the second node to look for a node on the first node's server. Note that the name of the discovery setting has changed to `discovery.seed_hosts` in Elasticsearch 7.x. ---

Also, vitally, in 6.5.4 you _must_ set `discovery.zen.minimum_master_nodes` to `2` if you have two master-eligible nodes. If you do not then your two-node cluster could split into two one-node clusters at a later date. ---
