Hi,I try to 3 nodes cluster for ES7.4.  
but only one node found in cluster and not specific error after restart ES.

Configurations and node list data are below,

node1  
cluster.name: my\_cluster  
node.name: {HOSTNAME} node.master: true node.data: true network.host: 192.168.9.40 discovery.seed\_hosts: ["192.168.9.40","192.168.9.41", "192.168.9.42"] cluster.initial\_master\_nodes: ["192.168.9.40","192.168.9.41", "192.168.9.42"] xpack.security.enabled: false node2 cluster.name: my\_cluster node.name: {HOSTNAME}  
node.master: true  
node.data: true  
network.host: 192.168.9.41  
discovery.seed\_hosts: ["192.168.9.40","192.168.9.41", "192.168.9.42"]  
cluster.initial\_master\_nodes: ["192.168.9.40","192.168.9.41", "192.168.9.42"]  
xpack.security.enabled: false

node3  
cluster.name: my\_cluster  
node.name: ${HOSTNAME}  
node.master: true  
node.data: true  
network.host: 192.168.9.42  
discovery.seed\_hosts: ["192.168.9.40","192.168.9.41", "192.168.9.42"]  
cluster.initial\_master\_nodes: ["192.168.9.40","192.168.9.41", "192.168.9.42"]  
xpack.security.enabled: false

Hi @oqto

1. What happens when you try to connect the ports 9200 (HTTP) and 9300 (Transport) from the nodes? You should get an answer from every node on 9200 and the connection should not be possible when connecting to 9300.
2. Are the necessary firewall ports open?
3. Could you please share the logs from Elasticsearch?
