I want to set up an elasticsearch cluster using docker swarm with three nodes on three separate servers. But when I do the **docker stack deploy** command and the service comes up, ![NaNtC](https://us1.discourse-cdn.com/elastic/original/3X/6/3/637e136f8f6bc5354ced92f3d8ee19ebd1e066bb.png) but I get docker logs from the container, there are errors on all three. node ---\> ubuntu1 ```auto {"@timestamp":"2023-12-09T14:11:54.628Z", "log.level": "WARN", "message":"address [10.0.12.8:9300], node [null], requesting [false] discovery result: [es02][10.0.0.29:9300] connect_exception: Failed execution: io.netty.channel.ConnectTimeoutException: connection timed out: 10.0.0.29/10.0.0.29:9300: connection timed out: 10.0.0.29/10.0.0.29:9300", "ecs.version": "1.2.0","service.name":"ES_ECS","event.dataset":"elasticsearch.server","process.thread.name":"elasticsearch[es03][generic][T#4]","log.logger":"org.elasticsearch.discovery.PeerFinder","elasticsearch.node.name":"es03","elasticsearch.cluster.name":"my-cluster"} {"@timestamp":"2023-12-09T14:11:58.273Z", "log.level": "WARN", "message":"master not discovered yet, this node has not previously joined a bootstrapped cluster, and this node must discover master-eligible nodes [es01, es02, es03] to bootstrap a cluster: have discovered [{es03}{58joxi_jQPqr8cd0eHxySg}{uIrh9xE3SNGyLtZc6DAUUA}{es03}{10.0.0.25}{10.0.0.25:9300}{cdfhilmrstw}{8.10.4}{7000099-8100499}];
