ERROR: Aborting enrolling to cluster. Could not communicate with the node on any of the addresses from the enrollment token. All of [ip:9200] were attempted

Hi,

I tried to join new node to existing Elastic cluster.
I'm using Elasticsearch version 8.4.1

Tried steps for new node:

  1. sudo rpm --install elasticsearch-8.4.1-x86_64.rpm
  2. /usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token

I got this error at 2nd step.

Existing cluster (single node-cluster) configuration:
node1
cluster.name: my-application
node.name: node1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0

cluster.initial_master_nodes: ["localhost.localdomain"]

This node will be reconfigured to join an existing cluster, using the enrollment token that you provided.
This operation will overwrite the existing configuration. Specifically:

  • Security auto configuration will be removed from elasticsearch.yml
  • The [certs] config directory will be removed
  • Security auto configuration related secure settings will be removed from the elasticsearch.keystore
    Do you want to continue with the reconfiguration process [y/N]y
    Unable to communicate with the node on https://ip node1:9200/_security/enroll/node. Error was No route to host
    ERROR: Aborting enrolling to cluster. Could not communicate with the node on any of the addresses from the enrollment token. All of [ip node1:9200] were attempted.

Thank You...!
