mysql data node not connecting to node manager on AWS EC2

I am trying to setup mySql manager + data node + sql server (Server A) and another data node cluster on (Server B). Both running on Ubuntu 16.04 amd_64 **Server A** */etc/hosts* also on Server B Both private ip 172.xx.xx.xx ip-172-xx-xx-xx-eu-west-1.compute.internal 172.xx.xx.xx ip-172-xx-xx-xx.eu-east-1.compute.internal */config.ini* [ndbd default] NoOfReplicas=2 # Number of replicas [ndb_mgmd] hostname=ip-172-xx-xx-xx.eu-west-1.compute.internal show Connected to Management Server at: 172.xx.xx.xx:1186 <- A Cluster Configuration --------------------- [ndbd(NDB)] 1 node(s) id=2 (not connected, accepting connect from 172.xx.xx.xx) <- B [ndb_mgmd(MGM)] 1 node(s) id=1 @172.x.x.x (mysql-5.7.22 ndb-7.6.6) [mysqld(API)] 1 node(s) id=3 (not connected, accepting connect from 172.xx.xx.xx) <- A Not sure how would i connect to mysqld(API) that should work fine after i installed the server/client cluster. Also i got inbound on both Instances A & B to accept all traffic between all port ranges 1000-60000 just in case i am missing something, and outbound is open to everything. I wonder what is it i am missing, i got so tired today trying to find out what is going on with the setup. Any help will be appreciated !
