It looks like you're trying to connect to Cassandra on your local machine, on the default port of 9042.

If this is not working, I would check the following:

  • Cassandra is indeed running on your local machine (verify with nodetool status).
  • Either listen_address or rpc_address are bound to localhost. The address shown in the output of nodetool status is the address that should be used to connect.
  • You are providing the correct username and password, if CassandraAuthorizer and PasswordAuthenticator are being used.
  • You are providing the correct SSL/TLS certificate if client-to-node SSL is enabled.
  • Also, as of Cassandra 4.0, connecting with client-to-node SSL enabled now happens on port 9142, while regular, unencrypted traffic is still on 9042.
