[SOLVED] Spring Redisson Sentinel Error - At least two sentinels are required

I am using Sentinel mode for Redis. I am using Redisson Client version 3.9.1

<dependencies>
    <dependency>
        <groupId>org.redisson</groupId>
        <artifactId>redisson-spring-data-20</artifactId>
        <version>${redisson-version}</version>
    </dependency>
    <dependency>
        <groupId>org.redisson</groupId>
        <artifactId>redisson</artifactId>
        <version>${redisson-version}</version>
    </dependency>
</dependencies>

The configuration of Sentinel using Redisson:

@EnableCaching
public class RedisCache {

    @Autowired
    private ObjectMapper objectMapper;

    @Bean
    public RedissonClient redissonClient() {
        Config config = new Config();
        config.setCodec(new JsonJacksonCodec(objectMapper));

        config.useSentinelServers()
                    .setMasterName("redis-master")
                    .addSentinelAddress("redis://localhost:26378")
                    .addSentinelAddress("redis://localhost:26379");

        return Redisson.create(config);
    }

    @Bean
    public RedissonConnectionFactory redissonConnectionFactory(RedissonClient redisson) {
        return new RedissonConnectionFactory(redisson);
    }
}

I am running two sentinel servers and one Redis master with no slave. This is just a setup on my local environment.
Output of some commands:

redis-cli -p 26379
127.0.0.1:26379> SENTINEL get-master-addr-by-name redis-master
1) "127.0.0.1"
2) "6379"
redis-cli -p 26378
127.0.0.1:26378> SENTINEL get-master-addr-by-name redis-master
1) "127.0.0.1"
2) "6379"

Whenever I am running my Spring Boot Application, I get the following error:

       Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'redissonClient' defined in class path resource [xxxx/cache/impl/redis/config/RedisCache.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: At least two sentinels should be defined in Redis configuration!

How do I resolve this error?

PS: I have tried master-slave configuration also, with one sentinel attached to the host and other one attached to the slave, but the error remains the same. I have tried sentinels running on different local machines with different private IPs, but the error remains the same. Tried with 3 sentinel servers, no benefits.
