ES8.14 has 5 nodes. But master was down and reinstalled. How to join the new cluster?

1. ES8.14 has 5 nodes. But master[node-04] was down and reinstalled.
2. The current es cluster is running well with new master[node-05].
3. I generated the "/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node" in node-02.
4. Executed the "/usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token newToken" in node-04.
   Unable to communicate with the node on http s://node-04:9200/_security/enroll/node. Error was Connection refused
   ERROR: Aborting enrolling to cluster. Could not communicate with the node on any of the addresses from the enrollment token. All of [node-04:9200] were attempted., with exit code 69
5. "elasticsearch-create-enrollment-token -s node" will generate new token based on the old master value [node-04] in elasticsearch.yml, not from the new master[node-05]. Right?
   Like this scenario, how can I let node-04 join the new cluster?

• I generated the "/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node" in node-02.
• Executed the "/usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token newToken" in node-04.
  Unable to communicate with the node on http s://node-04:9200/_security/enroll/node. Error was Connection refused

That error message doesn't align with the steps you say you took.

If you generated a token on node-02 then the error message should not be mentioning node-04.

Can you double check that what you've written above is exactly what happened?
