Предупреждение о встроенном кластере приложения Hazecast-Kubernetes Springboot

Я развернул встроенный кластер hazelcast на Kubernetes, я получаю предупреждение ниже. отключен флаг автоматического увеличения, а ошибка portCount по-прежнему отображается.

Конфиг:

Config config = new Config();
config.setClusterName("cache-cluster");
JoinConfig joinConfig = config.getNetworkConfig().getJoin();
joinConfig.getMulticastConfig().setEnabled(false);
joinConfig.getTcpIpConfig().setEnabled(false);
joinConfig.getKubernetesConfig().setEnabled(true)
            .setProperty("namespace", "<Namespace>")
            .setProperty("service-name", "<Service-name>");

Я открыл контейнерный порт в Кубернетесе. сервисы могут создавать кластер, но постоянно получают предупреждение, указанное ниже.

Не уверен, почему здесь происходит соединение

[22.249.47.234]:5701 [cache-cluster] [4.0.1] Connection[id=4, **/22.249.47.234:5701->/22.249.55.1:52736**, qualifier=null, endpoint=null, alive=false, connectionType=NONE] closed.

отсутствует какая-либо конфигурация?
