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 Exception

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)
                        .setAtomicityMode(TRANSACTIONAL)
                        .setCacheMode(PARTITIONED)
                        .setBackups(2)
                        .setWriteSynchronizationMode(PRIMARY_SYNC));
 }catch (Exception e) {
                LOGGER.error("get cache [{}] not success", cacheName, e);
                LOGGER.error("get address info [{}], ipfinder [{}]", clientConfiguration.getAddresses(), clientConfiguration.getAddressesFinder().getAddresses());

                retrySleep();
            } finally {
                retryTimeTmp++;
            }
