Соединение Hazelcast отказалось обратиться к x ⇐ JAVA

[Anonymous]

У меня есть очень простой клиент Hazelcast, который я использую для подключения к кластерному экземпляру. Видите, что я подключаюсь как к локальному хосту (127.0.0.1), так и к удаленному серверу (xxx.xx.xx.x).

Код: Выделить всё

public HazelcastCacheClient(String mapName, Map cacheMap) {

Config cfg = new Config();
NetworkConfig networkConfig = cfg.getNetworkConfig();
networkConfig.setPort(5701);
networkConfig.setPortCount(1);

JoinConfig joinConfig = networkConfig.getJoin();
joinConfig.getMulticastConfig().setEnabled(false);
joinConfig.getAwsConfig().setEnabled(false);
joinConfig.getTcpIpConfig()
.addMember("127.0.0.1, xxx.xx.xx.x").setEnabled(true);

HazelcastInstance instance = Hazelcast.newHazelcastInstance(cfg);

Map map = instance.getMap(mapName);
}

Я открыл порты 5701-5710 на сервере CentOS (xxx.xx.xx.x), но в журналах вижу следующее:

Как видите, проблем с подключением к локальному хосту (127.0.0.1) нет, но к удаленному серверу xxx.xx.xx.x он не может подключиться. Я включил доступ к порту через брандмауэр на сервере CentOS для 5701.

Обратите внимание на следующую строку:
INFO: [127.0.0.1]:5701 [dev] [3.5.5] Не удалось подключиться к: xxx.xx.xx.x/xxx.xx.xx.x:5701. Причина: SocketException [Соединение отказалось использовать адрес xxx.xx.xx.x/xxx.xx.xx.x:5701]
