自己在阿里云的ECS（配置是1G ,1核）上搭建了一个redis集群（端口7000-7005），在服务器上测试

redis-cli -c -ip -p 7000

执行set，get方法的时候能够正确的重定向slot(定向到公网ip+端口，创建的时候是用公网ip创建的)
而且自己在电脑上的虚拟机上使用，和另外一台阿里云服务器

redis-cli -c -h 我的公网ip -p 7000

都能够正常访问，而且能够正确的重定向slot
但是我用Java的jedisCluster操作的时候就老是出现下面的问题

百度了好久，试了各种方法都不能解决问题，ESC的安全组配置也开放了7000-7005端口（0.0.0.0/0）和17000-17005（0.0.0.0/0）
redis.conf的配置文件

daemonize yes
appendonly yes
protected-mode no
cluster-enabled yes
cluster-node-timeout 15000
port 7000
cluster-config-file nodes-7000.conf

是不是因为阿里云服务器的问题导致的JedisCluster连接超时，想请各位大佬帮忙解决问题，停在这里好久了。
Java测试代码

        Set<HostAndPort> hostandports = new HashSet();
        hostandports.add(new HostAndPort("公网Ip",7000));
        hostandports.add(new HostAndPort("公网Ip",7001));
        hostandports.add(new HostAndPort("公网Ip",7002));
        JedisCluster jedisCluster = new JedisCluster(hostandports);
        System.out.println(jedisCluster.set("132455","aaaaaaaaaaaaa"));;
        System.out.println(jedisCluster.get("aaaaaa"));
