I need some help，
I tried to connect to my local RocketMQ service, but this exception left me confused
Here's my code ，thanks
``` java
public static void main(String[] args){
ClientServiceProvider provider = ClientServiceProvider.loadService();
ClientConfiguration configuration = ClientConfiguration.newBuilder()
.setRequestTimeout(Duration.ofSeconds(10))
.setEndpoints("172.18.98.74:9876")
.build();
try {
Producer producer = provider.newProducerBuilder()
.setClientConfiguration(configuration)
.build();
Message message = provider.newMessageBuilder()
.setTopic("TOPIC_TEST")
.setBody("HelloWorld".getBytes())
.build();
producer.send(message);
} catch (ClientException e) {
e.printStackTrace();
}
}
```
Console message
```

> Have you started rocketmq proxy?
Thank you for your reminder. I checked the proxy service, opened the port, and changed the connection address to the proxy service port. Now the problem is solved.
