Kubernetes cannot access Cassandra within same namespace - kubernetes

Question

I get
All host(s) tried for query failed (tried: 10.244.0.72/10.244.0.72:9042 (com.datastax.driver.core.exceptions.TransportException: [10.244.0.72/10.244.0.72:9042] Channel has been closed))
when trying to access Cassandra within the same namespace. Although when I forward ports it works ok from localhost. keyspace is created successfully.
kubectl port-forward cassandra1-0 9042:9042

changed ownership of '/cassandra_data/data' from root to cassandra
changed ownership of '/cassandra_data' from root to cassandra
In my application that runs in the same namespace i tried setting cassandraport to 9042 and host to:
10.240.0.4 (hostIP)
10.244.0.72 (podIP)
cassandra1 (name of the service)
cassandra1.default
cassandra1.default.svc.cluster.local
cassandra1-0.cassandra1.default.svc.cluster.local
_cql._tcp.cassandra1.default.svc.cluster.local
I also tried different types of a service:
headless, ClusterIP, NodePort
Does anybody has ANY ideas what is wrong or what else can i try to get this to work?
