我尝试使用this chart将elasticsearch和kibana部署到kubernetes，并在kibana容器内得到此错误，因此入口返回503错误，容器从未准备好。
错误：

[2022-11-08T12:30:53.321+00:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. socket hang up - Local: 10.112.130.148:42748, Remote: 10.96.237.95:9200

Ip地址10.96.237.95是有效的ElasticSearch服务地址，端口正确。
当我在kibana容器中执行curl to elasticsearch时，它成功地返回了一个响应。
我的配置中是否遗漏了什么？

UPD：用其他映像版本（8. 4. 1）试过了，什么都没有改变，我得到了同样的错误。顺便说一下，logstash成功地将日志运送到这个elasticsearch示例，所以我认为问题出在kibana。
