ignite client can not reconnect to ignite Kubernetes cluster,after pod restart

below if client code config
KubernetesConnectionConfiguration kcfg = new
KubernetesConnectionConfiguration();

kcfg.setNamespace(igniteK8sNameSpace);kcfg.setServiceName(igniteK8sServiceName);cfg.setAddressesFinder(new
ThinClientKubernetesAddressFinder(kcfg));cfg.setRetryPolicy(new
ClientRetryAllPolicy());


after ignite pod restart

client throw Exceptionorg.apache.ignite.client.ClientConnectionException:

and i use retry to reconnect and print
clientConfiguration.getAddressesFinder().getAddresses() and it address is
pod address,but client not reconnect

while (retryTimeTmp < retryTimes) {
  try {
                return igniteClient.getOrCreateCache(new
ClientCacheConfiguration()
                        .setName(cacheName)

                LOGGER.error("get address info [{}], ipfinder [{}]",
clientConfiguration.getAddresses(),

                retrySleep();
