排查过程：
网上有说防火墙的(试了不行)；有说zk版本的(这边还是第三方包间接依赖的，且有包冲突，试了去掉一个没好使);

解决方案：
修改了超时时间

ZookeeperConfiguration zookeeperConfiguration = new ZookeeperConfiguration(serverList, namespace);
zookeeperConfiguration.setSessionTimeoutMilliseconds(600000);
zookeeperConfiguration.setConnectionTimeoutMilliseconds(600000);
zookeeperConfiguration.setMaxSleepTimeMilliseconds(30000);
zookeeperConfiguration.setBaseSleepTimeMilliseconds(10000);
ZookeeperRegistryCenter regCenter = new ZookeeperRegistryCenter(zookeeperConfiguration);
