Unable to form Elasticsearch 7 cluster on EC2 machines

I have following configuration setup on two AWS ec2 machines.

    Machine 10.0.66.123
    ----------------------
    cluster.name: uat-es-cluster
    node.name: uat-es-1
    path.data: /var/lib/elasticsearch
    path.logs: /var/log/elasticsearch
    network.host: 10.0.66.123
    discovery.seed_hosts: ["10.0.66.106", "10.0.66.123"]
    cluster.initial_master_nodes: ["10.0.66.106", "10.0.66.123"]
    node.master: true


    Machine 10.0.66.106
    ----------------------
    cluster.name: uat-es-cluster
    node.name: uat-es-2
    path.data: /var/lib/elasticsearch
    path.logs: /var/log/elasticsearch
    network.host: 10.0.66.106
    discovery.seed_hosts: ["10.0.66.123", "10.0.66.106"]
    cluster.initial_master_nodes: ["10.0.66.106", "10.0.66.123"]
    node.master: true

I am getting following log on both nodes.

I was missing inbound rule for TCP, port 9300 in ec2 instance's security group.

Put in the following into your elasticsearch.yml of your master node.

cluster.initial_master_nodes: - node_name_or_ip

Start the first node and then the rest of the nodes.
