Briefly, this error occurs when Elasticsearch fails to authenticate a user or service trying to access its resources. This could be due to incorrect credentials or a misconfigured security realm. To resolve this issue, you can: 1) Verify the credentials being used for authentication. 2) Check the configuration of the security realm in Elasticsearch. 3) Ensure that the user or service has the necessary permissions to perform the requested action. 4) If using a third-party security realm, ensure it’s correctly integrated with Elasticsearch.
