Remote Cluster node 9300 port cannot connect

[rachelyang]

I am connecting a remote cluster from the local cluster. I got a connection time out error. Then I tried to curl the 9200 and 9300 port from the local cluster note to the remote cluster node. This is the response:

curl -X GET elastic:*** http://remotenode01ip:9200

    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

curl -X GET -k -u elastic:*** https://remotenode01ip:9300
curl: (56) OpenSSL SSL_read: error:0A000412:SSL routines::sslv3 alert bad certificate, errno 0

I have set up the same CA for the local and remote cluster xpack.security.transport.ssl.
What else should I set up to connect 9300 port?
Thank you.

I am connecting a remote cluster from the local cluster. I got a connection time out error.

Please provide more details on this step.

What exactly did you configure? What is the exact error message? Are there any other details on the logs on either cluster?
