我正在尝试使用 Java Api 和屏蔽连接到我的 Elasticsearch 服务器。我可以使用 sense 插件（例如）和通过 curl 在 9200 上执行索引、获取、删除和搜索操作。带防护罩的 Elasticsearch 网络服务器。
我使用相同的 API 连接到我的 elasticsearch 本地主机，它运行良好，但是当我尝试连接我的网络服务器时，我总是得到同样的错误：
错误

Java代码：
TransportClient client = TransportClient.builder()
.addPlugin(ShieldPlugin.class)
.settings(Settings.builder()
.put("cluster.name", ClusterName)
.put("shield.user", "USER:PASSWORD")
.build())
.build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(HOST), 9300));
我已经尝试过无法使用 Java API 连接到 ElasticSearch 服务器以同步我的 Java API Java 版本和我的服务器，目前我正在使用：
Java API：
C:\Program Files\Java\jdk1.8.0_92
服务器：
"version": "1.8.0_91",
"vm_name": "OpenJDK 64-Bit Server VM",
我不知道使用 ...0_91 和 0_92 是否有任何问题，但似乎没有任何区别，因为 java API 在我的本地主机服务器上运行良好。
如果您需要更多信息，请随时询问。提前致谢！
更新：
我在 elasticsearch.yml 中所做的更改
shield.ssl.keystore.path: /usr/share/elasticsearch/bin/shield/elastic.jks
shield.ssl.keystore.password: password
shield.ssl.keystore.key_password: password
shield.transport.ssl: true
shield.http.ssl: true
shield.https.ssl: true
network.host: HOST_IP
network.publish_host: HOST_IP
shield.ssl.hostname_verification.resolve_name: false
https://HOST:9200/_cluster/health?pretty=true 的结果

更新2：
我已经尝试根据官方文档激活 SSL，但出现以下错误：

临时解决方案
在那次尝试之后，我按照Vladislav Kysliy 的建议做了并禁用了 SSL，它确实有效，但我正在寻找一个真正的解决方案，而不是一个临时的解决方案。
