This error means that the API Gateway client cannot connect to the Cassandra server.

To resolve this issue, perform the following steps:

  • Enable Cassandra debug logging.
  • Contact your network administrator

For more details on Cassandra configuration, see Install Apache Cassandra in the API Gateway Installation Guide.
