Unable to obtain session. Cassandra hasn't been started or is unavailable.

Hello! In my Pega 8.3 application, when I start it up, I get the following errors w/ Cassandra.

[service: VBD.Default] [ STANDARD] [ ] [ ] (rvice.operation.StartOperation) ERROR - Cannot start service [VBD.Default]. Will retry in 180 seconds. Remaining attempts: 2
com.pega.dsm.dnode.api.dds.service.SessionNotAvailableException: Unable to obtain session. Cassandra hasn't been started or is unavailable

Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /XXX.XXX.XX.XX:9042 (com.datastax.driver.core.exceptions.TransportException: [/XXX.XXX.XX.XX:9042] Cannot connect))

How can I fix this error and get a clean log file? Via a DSS setting?

Thanks!
