I can't connect Redis cluster

[soulshuangchen]

I use this code to create cluster, but it has a problem:

cluster, err := clust.NewCluster(
		&clust.Options{
			StartNodes:   []string{"10.151.3.24:6379", "10.151.3.24:6383", "10.151.3.24:6381"},
			ConnTimeout:  5 * time.Second,
			ReadTimeout:  5 * time.Second,
			WriteTimeout: 5 * time.Second,
			KeepAlive:    16,
			AliveTime:    60 * time.Second,
		})

NewCluster: no valid node in [10.151.3.24:6379 10.151.3.24:6383 10.151.3.24:6381]

but when I use "github.com/gomodule/redigo/redis" to create Redis.conn it was worked.
this is codes:

var RedisPool *redis.Pool
var ip = "10.151.3.24:6381"
func NewRedisPool(ip string) *redis.Pool {
	return &redis.Pool{
		MaxIdle:     6,
		IdleTimeout: 240 * time.Second,
		Dial: func() (redis.Conn, error) {
			c, err := redis.Dial("tcp", ip)
			if err != nil {
				return nil, err
			}
			return c, nil
		},
		TestOnBorrow: func(c redis.Conn, t time.Time) error {
			if time.Since(t) < time.Minute {
				return nil
			}
			_, err := c.Do("PING")
			return err
		},
	}
}
RedisPool = NewRedisPool(ip)
redisConn := RedisPool.Get()
defer redisConn.Close()

redisConn.Do("AUTH", "123456")
reply, err := redisConn.Do("set", "demo_key", "666")

I don't know what cause this problem. What Redis cluster need? I use Virtualmachine+Docker to create Redis cluster.What should I do to handle this problem. Please help me.Thanks

I get the same error:
NewCluster: no valid node in [localhost:6379]
Also tried connecting to redis with github.com/garyburd/redigo/redis and it works just fine, Dial, PING, SET, GET commands are working just fine.
I'm just unable to get it working with this repo.

Redis version: 5.0.7

I got the similar error:

redis-server cluster is running normally.

this problem caused by errcode "ECONNTIMEOUT", you should close cluster conn after use cluster
defer cluster.Close()
