WebServerException: Unable to start embedded Tomcat

I want to debug my spring-boot application but I couldnt launch the debugger mode on Intellij IDE.

I am getting following errors

Caused by: org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat

RedisConfig class

@Configuration
@EnableRedisRepositories
public class RedisConfig {

    @Value("${spring.redis.password:}")
    private String redisPassword;

    @Bean
    @Primary
    JedisConnectionFactory jedisConnectionFactory(RedisProperties redisProperties) {
        RedisStandaloneConfiguration redisStandaloneConfiguration =
                new RedisStandaloneConfiguration(redisProperties.getRedisHost(), redisProperties.getRedisPort());
        redisStandaloneConfiguration.setPassword(RedisPassword.of(redisPassword));
        return new JedisConnectionFactory(redisStandaloneConfiguration);
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate(JedisConnectionFactory connectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(connectionFactory);
        return template;
    }

}

RedisProperties class

@Configuration
public class RedisProperties {
    private final int redisPort;
    private final String redisHost;

    public RedisProperties(
            @Value("${spring.redis.port}") int redisPort,
            @Value("${spring.redis.host:localhost}") String redisHost) {
        this.redisPort = redisPort;
        this.redisHost = redisHost;
    }

    public int getRedisPort() {
        return redisPort;
    }

    public String getRedisHost() {
        return redisHost;
    }
}

application - properties

spring:
  profiles: local
  redis:
    host: localhost
    port: 6340
  application:
    name: fxg-lhl-schedule-svc
server.port: 9092

At this point I followed and tried most of the solutions that are out there on similar troubleshooting threads but no luck so far.

I want to know how can I resolve this?

Provide a default value like below -

@Value("${spring.redis.port:6340}")
