The master logs are giving you a big hint: > [@bruno\_aleixo](#): > > [node-3] master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and **[cluster.initial\_master\_nodes] is empty on this node** You have set `cluster.initial_master_nodes` on the two non-master nodes (where it is ignored) but not on the master node (where it is required the first time the cluster starts). Also you should set it to the `node.name` property not an IP address: ```auto cluster.initial_master_nodes: ["node-3"] ``` ---

Very thanks @DavidTurner, but i add the config **[cluster.initial\_master\_nodes]** in the nodes too, would have a problem? again very thanks ---

Sorry, I don't really understand what you're asking here. Does [the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/discovery-settings.html#initial_master_nodes) help at all? ---
