RedisConnectionException: Unable to init enough connections amount

Today I start the spring boot project in MacBook Pro with M1 pro(with 8 performance core and 2 efficient core), shows error:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'redissonClient' defined in class path resource [misc/redisson/RedissonConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.redisson.api.RedissonClient]: Factory method 'redissonClient' threw exception; nested exception is org.redisson.client.RedisConnectionException: Unable to init enough connections amount! Only 10 of 24 were initialized.

the remote redis was a single redis master server with 2 slaves. my redission config look like this:

package misc.redisson;import org.redisson.Redisson;import org.redisson.api.RedissonClient;import org.redisson.config.Config;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;/** * @author dolphin * @version 1.0 * @date: 2020/9/5 9:50  */@Configurationpublic class RedissonConfig {    @Value(value = "${spring.redis.host}")    private String redisHost;    @Value(value = "${spring.redis.port:6379}")    private Integer redisPort;    @Value(value = "${spring.redis.timeout:2000}")    private Integer redisTimeOut;    @Value(value = "${spring.redis.password}")    private String redisPwd;    @Bean(name = "redissonClient")    public RedissonClient redissonClient() {        Config config = new Config();        config.useSingleServer()                .setAddress("redis://" + redisHost +":" + redisPort)                .setPassword(redisPwd)                .setTimeout(redisTimeOut)                .setDatabase(1);        RedissonClient redissonClient = Redisson.create(config);        return redissonClient;    }}

and the redis server(2Core and 8GB memory in the cloud) max client config:

connected_clients120cluster_connections0maxclients10000

the remote server was a single kubernetes node, and connected local machine and remote server by telepresence. why did this happen? what should I do to fixed this problem?
