Redis closing connection after request

So i'm using java with spring data redis 2.4.8 for caching, when i'm trying to get values from cache (i have a list of keys), in logs i see that redis always closing connection:

2024-04-02 09:16:14.851 DEBUG 1655457 --- [nio-8080-exec-3] o.s.d.redis.core.RedisConnectionUtils    : Fetching Redis Connection from RedisConnectionFactory2024-04-02 09:16:14.943 DEBUG 1655457 --- [nio-8080-exec-3] o.s.d.redis.core.RedisConnectionUtils    : Closing Redis Connection.2024-04-02 09:16:14.944 DEBUG 1655457 --- [nio-8080-exec-3] o.s.d.redis.core.RedisConnectionUtils    : Fetching Redis Connection from RedisConnectionFactory2024-04-02 09:16:15.035 DEBUG 1655457 --- [nio-8080-exec-3] o.s.d.redis.core.RedisConnectionUtils    : Closing Redis Connection.2024-04-02 09:16:15.036 DEBUG 1655457 --- [nio-8080-exec-3] o.s.d.redis.core.RedisConnectionUtils    : Fetching Redis Connection from RedisConnectionFactory2024-04-02 09:16:15.127 DEBUG 1655457 --- [nio-8080-exec-3] o.s.d.redis.core.RedisConnectionUtils    : Closing Redis Connection.

How to make connection keep alive ? Here is my config:

    @Bean    public RedisConnectionFactory redisConnectionFactory() {        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();        redisStandaloneConfiguration.setHostName(redisHost);        redisStandaloneConfiguration.setPort(redisPort);        redisStandaloneConfiguration.setPassword(redisPassword);        redisStandaloneConfiguration.setDatabase(redisDbName);        LettuceClientConfiguration.LettuceClientConfigurationBuilder builder = LettuceClientConfiguration.builder();        builder.clientOptions(ClientOptions.builder().autoReconnect(true)                .socketOptions(SocketOptions.builder().keepAlive(true).build())                .build()).useSsl();        return new LettuceConnectionFactory(redisStandaloneConfiguration, builder.build());    }    @Bean    public RedisTemplate<String, Object> redisTemplate() {        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();        redisTemplate.setConnectionFactory(redisConnectionFactory());        redisTemplate.setDefaultSerializer(new GenericJackson2JsonRedisSerializer(objectMapper));        return redisTemplate;    }

I found the KeepAlive setting in the socket options, but it didn't help. .socketOptions(SocketOptions.builder().keepAlive(true).build())
