不能连接数据库

各位好，

我想将iotdb集群部署到GKE(Google Kubernetes Engine)的load balancer上面实现自动扩容。

目前已经把iotdb集群部署到external load balancer了。 log 没有报错，本地端测试pod也是正常，但是external load balancer生成的终端(endpoint)无法连接数据库。

不知道用什么办法解决这个问题？谢谢！

Start by reviewing the GKE external load balancer setup and the attached screenshots, then compare endpoint connectivity with the local pod test that succeeds. Done means identifying why the generated endpoint cannot connect to the IoTDB cluster and documenting a reproducible fix.
