I wanted to connect 2 elastic clusters (7.10) with the remote cluster, to see indices on one kibana. my two clusters are on Kubernetes. first I tried to configure the elastic Ip with endpoint( I use ingress), do you know if this possible I did not succeeded? After that, I also expose a node port but I still can't connect to remote elastic.(when I did curl on remote elastic cluster it worked curl 192.88.188.88:3333

{
  "error" : {
    "root_cause" : [
      {
        "type" : "connect_transport_exception",
        "reason" : "[]] handshake_timeout[30s]"
          }

can you please assist what I did wrong?
