Why is this not working?

Getting the following error:

Dse.NoHostAvailableException: 'None of the hosts tried for query are available

with the following connection code:

IDseCluster dseCluster = DseCluster.Builder()
                .AddContactPoint("ourdomain.com").WithPort(9042)
                .WithAuthProvider(new DsePlainTextAuthProvider("---username--", "---password---"))
                .WithGraphOptions(new GraphOptions().SetName("DSE_GRAPH_QUICKSTART"))
                .Build();

            IDseSession session = dseCluster.Connect();
