org.apache.thrift.transport.TTransportException: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?

Question

Am trying to enable node-to-node and client-to-node ssl encrytion in Datastax dse 3.2.3. First I tried to enable node-to-node it worked fine and started with out any error and then I added the client-to-node encryption options in the cassandra.yaml file, then it started throwing errors to me

My cassandra.yaml file looks like this.

server_encryption_options:
    internode_encryption: all
    keystore: /path/to/.keystore
    keystore_password: xxxxx
    truststore: /path/to/.truststore
    truststore_password: xxxxx



client_encryption_options:
    enabled: true
    keystore: /path/to/.keystore
    keystore_password: xxxxx
    truststore: /path/to/.truststore
    truststore_password: xxxxx
    protocol: ssl
    store_type: JKS
    cipher_suites: [TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA]

Answer 1

This error means that you have a client which is attempting to open an unencrypted connection.
