Hi there ! I Set up basic security for the Elastic Stack plus secured HTTPS traffic . and then my kibana can connect to the local cluster successfully . But there is something wrong with the connection between the localcluster and the remote cluster.

```auto
{
  "remoting_cluster" : {
    "connected" : false,
    "mode" : "sniff",
    "seeds" : [
      "10.112.51.39:9200"
    ],
    "num_nodes_connected" : 0,
    "max_connections_per_cluster" : 3,
    "initial_connect_timeout" : "30s",
    "skip_unavailable" : false
  }
}

```

Here is the log of local cluster node:

```auto

Hi , I have already solved this problem. The local cluster communicate with the remote cluster on the port 9300 , I set it to 9200 😅.
