Nodes are not joining cluster

Elastic Stack Elasticsearch
1

Hello,

I am trying to build a 3-node Elasticsearch cluster. I am using Elasticsearch 7.3. When I check the health of the cluster, it tells me the number of nodes = 1.

Here are the node settings for all three:

Start config

Node 1:

cluster.name: elastic

node.name: node-1
node.data: true
node.ingest: true
node.master: true

network.host: 10.10.1.176
http.port: 9200

discovery.seed_hosts: ["10.10.1.176", "10.10.1.175", "10.10.1.174"]
cluster.initial_master_nodes: [node-1, node-2, node-3]

Node 2:

cluster.name: elastic

node.name: node-2
node.data: true
node.ingest: true
node.master: true

network.host: 10.10.1.175
http.port: 9200

discovery.seed_hosts: ["10.10.1.176", "10.10.1.175", "10.10.1.174"]
cluster.initial_master_nodes: [node-1, node-2, node-3]

Node 3:

cluster.name: elastic

node.name: node-3
node.data: true
node.ingest: true
node.master: true

network.host: 10.10.1.174
http.port: 9200

discovery.seed_hosts: ["10.10.1.176", "10.10.1.175", "10.10.1.174"]
cluster.initial_master_nodes: [node-1, node-2, node-3]

End config

[root@elk-node2 ~]# curl -X GET "10.10.1.176:9200/_cluster/health?pretty"

"cluster_name" : "elastic",

Seeing this error in the logs from Node1:

The message you quoted looks incomplete, and is missing the vital bits that would say what is wrong. Can you share the whole message?
