我正在尝试使用xpack安全性连接弹性搜索（6.5.4），但出现以下错误。
这是我的代码
Settings settings = Settings.builder()
.put("cluster.name", clusterName)
.put("xpack.security.user", username + ":" + password)
.build();
elasticSearchTransportClient = new PreBuiltXPackTransportClient(settings)
.addTransportAddresses(transportAddress);
我正在使用试用许可证。
