❌ An enrollment token to enroll new nodes wasn't generated. To add nodes and enroll them into this cluster:
• On this node:
  ⁃ Create an enrollment token with `bin/elasticsearch-create-enrollment-token -s node`.
  ⁃ Restart Elasticsearch.
• On other nodes:
  ⁃ Start Elasticsearch with `bin/elasticsearch --enrollment-token <token>`, using the enrollment token that you generated.
