java程序使用elasticjob3.x无法连接局域网内的zookeeper

[100kit]

java程序使用elasticjob3.x能连接本地zookeeper，但无法连接局域网内的其他zookeeper。
java程序换成elasticjob2.x可以连上，使用PrettyZoo也可以连上。

局域网zookeeper：centos7部署的zookeeper3.5.x、zookeeper3.6.4、zookeeper3.7.1都测试过；
centos7已关闭防火墙、关闭selinu、xswap；
网络能ping通；
spring项目依赖：elasticjob-lite-spring-boot-starter
普通java程序依赖：elasticjob-lite-core

你用telnet验证下，如果正常的话再排查代码问题
