Briefly, this error occurs when Elasticsearch fails to authenticate a user or process trying to perform an action due to incorrect or missing credentials. This could be due to incorrect configuration of the security settings or the user not having the necessary permissions. To resolve this issue, you can check and correct the security settings, ensure the user has the necessary permissions, or provide the correct credentials. If using X-Pack security, ensure it’s properly configured. Also, check the Elasticsearch logs for more detailed information about the error.

                            localNodeInfo.prefix; originAttributes(threadContext; message; localNodeInfo); token.principal(); action;
                            arrayToCommaDelimitedString(indices.get()); message.getClass().getSimpleName(); opaqueId());
                } else {
                    logger.info("{}[transport] [authentication_failed]\t{}; principal=[{}]; action=[{}]; request=[{}]{}";
