I have managed to get the node-to-node encryption between ElasticSearch nodes using the standard instructions given in the documentation.
Is it possible to use same certificates to get a TransportClient to connect to ElasticSearch? I continue to get an error about “unknown_certificate”. Does anyone have a good pointer to a set of instructions to get TransportClient to work?
Thanks and regards,
