Hi, I never used version 2.0.x but I think port 7000 isn't enough.
Try enable: 7000 inter-node 7001 SSL inter-node 9042 CQL 9160 Thrift is enable in that version And **In Cassandra.yaml, add property “broadcast_address”. = local ipv4 **In Cassandra.yaml, change “listen_address” to private IP. = local ipv4 As a starting point. Cheers.
