So the second line of your netstat output tells me about what is happening here.

tcp    0    0 10.142.0.3:7001    0.0.0.0:*    LISTEN

Port 7000 is used for inter-node communication within the cluster... Unless SSL is enabled. Then port 7001 is used.

  • Try port 7001 instead.
  • You're going to need a SSL cert from the same CA (certificate authority) as the other nodes in the cluster.

For SSL, have a look at the server_encryption_options and the client_encryption_options in the cassandra.yaml on the other nodes. That should give you a pretty good idea of what you need to connect.
