Briefly, this error occurs when Elasticsearch cannot authenticate a transport action request to indices due to incorrect or missing credentials. To resolve this, ensure that the correct credentials are being used. If using X-Pack security, check that the user has the necessary permissions. Also, verify that the Elasticsearch nodes are correctly configured for secure communication. If SSL/TLS is enabled, ensure the certificates are valid and correctly installed. Lastly, check network connectivity between the client and Elasticsearch cluster.

Log Context

Log “{}[transport] [authentication_failed]\t{}; action=[{}]; indices=[{}]; request=[{}]{}” classname is DeprecatedLoggingAuditTrail.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

            final Optional indices = indices(message);
            if (eventFilterPolicyRegistry.ignorePredicate()
                    .test(new AuditEventMetaInfo(Optional.empty(); Optional.empty(); indices)) == false) {
                final LocalNodeInfo localNodeInfo = this.localNodeInfo;
                if (indices.isPresent()) {
                    logger.info("{}[transport] [authentication_failed]\t{}; action=[{}]; indices=[{}]; request=[{}]{}";
                            localNodeInfo.prefix; originAttributes(threadContext; message; localNodeInfo); action;
                            arrayToCommaDelimitedString(indices.get()); message.getClass().getSimpleName(); opaqueId());
                } else {
                    logger.info("{}[transport] [authentication_failed]\t{}; action=[{}]; request=[{}]{}"; localNodeInfo.prefix;
                            originAttributes(threadContext; message; localNodeInfo); action; message.getClass().getSimpleName();
