Hazelcast refuses Member

Question

In our system, we have a Hazelcast cluster consisting of 2 nodes. Hazelcast is refusing the connection of the other member. What could be the reasons?

In the log file i see:

2017-10-13 17:39:25,419 [T:B_Hazelcast.IO.thread-Acceptor, C:] INFO  c.h.n.tcp.SocketAcceptorThread | [10.15.162.50]:5701 [ESB_Hazelcast] [3.7.2] **Accepting socket connection** from /10.15.162.51:33497

The server is instantiated with

public static HazelcastInstance createServer(Environment env) {
    com.hazelcast.config.Config hazelcastConfig = new com.hazelcast.config.Config();
    final String clusterName = env.getProperty("core.hazelcast.clusterName");
    hazelcastConfig.getGroupConfig().setName(clusterName);
    hazelcastConfig.getGroupConfig().setPassword(env.getProperty("core.hazelcast.clusterPassword"));

    JoinConfig joinConfig = hazelcastConfig.getNetworkConfig().getJoin();
    joinConfig.getMulticastConfig().setEnabled(false);
    joinConfig.getTcpIpConfig().setEnabled(true);
    final String members = env.getProperty("core.hazelcast.members");

    //Here it comes!!!
    if (!StringUtils.isEmpty(members)) {
        joinConfig.getTcpIpConfig().addMember(members);
    }
    hazelcastConfig.setProperty(GroupProperty.LOGGING_TYPE.getName(), "slf4j");
    return new HazelcastLifecycleBean(Hazelcast.newHazelcastInstance(hazelcastConfig));
}

In the configuration file is

core.hazelcast.members=10.15.162.50,10.15.162.51

And this is passed to joinConfig.getTcpIpConfig().addMember

Any ideas?

Please specify the port as part of your tcp member addresses. Instead of core.hazelcast.members=10.15.162.50,10.15.162.51 use core.hazelcast.members=10.15.162.50:5701,10.15.162.51:5701
