JedisCluster cannot connect to redis cluster with password - redis

Question

My redis cluster is listening to all interfaces and any hosts are allowed.
Telnet to redis is OK:
-NOAUTH Authentication required.
auth xxxx
+OK
get a
$1
a
iptables are empty:
[centos ]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination

But when I use JedisCluster:
redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
Caused by: java.net.ConnectException: Connection refused: connect
Let me show you the code:
//it's successful to connect to all master nodes and get the keys' value
#Test
public void testOneByOne() {
String[] keys = new String[] {
"b",
"c",
"a"
};
for (int i = 0; i < 3; i++) {
Jedis jedis = new Jedis("{myIp}", 5067 + i * 100);
jedis.auth("{myPassword}");
String a = jedis.get(keys[i]);
System.out.println(a); //ok
}
}
//all the masters and slaves can be connected, so network is ok.
#Test
public void testConnectFromSourceCode() throws Exception {
for (int i = 0; i < 6; i++) {
int port = 5067 + i * 100;
Socket socket = new Socket();
socket.setReuseAddress(true);
socket.setKeepAlive(true);
socket.setTcpNoDelay(true);
socket.setSoLinger(true, 0);
socket.connect(new InetSocketAddress("{myIp}", port), 2000);
socket.setSoTimeout(2000);
System.out.println("port=" + port + "," + socket.isConnected());//isConnected=true
}
}
//# error:
// redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool
//Caused by: java.net.ConnectException: Connection refused: connect
#Test
public void testJedisCluster() {
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxTotal(10);
jedisPoolConfig.setMaxIdle(5);
jedisPoolConfig.setMinIdle(5);
jedisPoolConfig.setMaxWaitMillis(300000);
jedisPoolConfig.setTestOnBorrow(true);
jedisPoolConfig.setTestOnReturn(true);
jedisPoolConfig.setTestWhileIdle(true);
HostAndPort hostAndPort = new HostAndPort("{myIp}", 5067);
JedisCluster jc=new JedisCluster(hostAndPort, 2000,2000,5, "{myPassword}", jedisPoolConfig);
String a = jc.get("a");
System.out.println(a);
}
Six intances(3 masters and 3 slaves) are in a single host, listening ports from 5067/5167/5267/5367/5467/5567
The redis cluster is installed in a TenCent Cloud Virtual Machine
I run my code in my own computer. The network is China Telecom family wide band.
I'm using:
redis 4.0.8
jedis 2.9.0
Thanks!
