I have the next issue in my project.
I want to connect my AWS-elasticache, but it's not possible
Here my configuration.
@Configuration@ComponentScan@EnableJpaRepositories@EnableRedisRepositoriespublic class RedisConfig { @Bean// to use in my local machine @ConditionalOnProperty(prefix = "redis", name = "cluster", havingValue = "not") public LettuceConnectionFactory redisConnectionFactory(@Value("${redis.host}") String host, @Value("${redis.port}") Integer port, @Value("${redis.password}") String password) { RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration(host, port); configuration.setPassword(password); return new LettuceConnectionFactory(configuration); } @Bean// configure to elasticaceh @ConditionalOnProperty(prefix = "redis", name = "cluster", havingValue = "yes", matchIfMissing = true) public LettuceConnectionFactory redisClusterConnectionFactory(@Value("${redis.host}") String host, @Value("${redis.port}") Integer port) { RedisClusterConfiguration clusterConfiguration = new RedisClusterConfiguration(); clusterConfiguration.clusterNode(host, port); return new LettuceConnectionFactory(clusterConfiguration);} @Bean public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory connectionFactory) { RedisTemplate<String, Object> template = new RedisTemplate<>(); template.setDefaultSerializer(new GenericJackson2JsonRedisSerializer()); template.setKeySerializer(new StringRedisSerializer()); template.setHashKeySerializer(new StringRedisSerializer()); template.setConnectionFactory(connectionFactory); return template; } @Bean @Qualifier("cacheManageMaster") public CacheManager cacheManager(LettuceConnectionFactory connectionFactory) { Duration expiration = Duration.ofHours(24); RedisCacheManager redisCacheManager = RedisCacheManager.builder(connectionFactory).cacheDefaults( RedisCacheConfiguration.defaultCacheConfig() .disableCachingNullValues() .serializeValuesWith( RedisSerializationContext.SerializationPair.fromSerializer( new GenericJackson2JsonRedisSerializer() ) ).entryTtl(expiration) ).build(); redisCacheManager.setTransactionAware(false); return redisCacheManager; }}But I got an exception, here stackTrace

I tried to connect with RedisInsight and it works
I check some issues that looks very similar, but nothing that help mehttps://github.com/redisson/redisson/issues/1625https://github.com/sixthpoint/spring-boot-elasticache-redis-tutorial/blob/master/src/main/java/com/sixthpoint/spring/boot/elasticcache/redis/config/RedisConfig.javahttps://levelup.gitconnected.com/how-to-connect-to-aws-elasticache-redis-in-spring-boot-app-9dd2e0908467https://docs.spring.io/spring-data/data-redis/docs/current/reference/html/#clusterhttps://github.com/netty/netty/issues/8261
Anyone could you know hoy to solve it?
