生产者无法发送消息，而消费者可以连接群集。第4.7.1版

我已经在VPS上部署了v4.7.1，并且明确地将brokerIP1和brokerIP2设置为公共IP。 然而，当我尝试用Java客户端发送消息时，它会不断抛出RemotingConnectException。以下是堆栈跟踪：

java.lang.IllegalStateException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to [namesrvIP:9876] failed at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:679) at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:509) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.tryToFindTopicPublishInfo(DefaultMQProducerImpl.java:693) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendDefaultImpl(DefaultMQProducerImpl.java:557) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.access$300(DefaultMQProducerImpl.java:97) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl$4.run(DefaultMQProducerImpl.java:511) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to [namesrvIP:9876] failed at org.apache.rocketmq.remoting.netty.NettyRemotingClient.getAndCreateNameserverChannel(NettyRemotingClient.java:445) at org.apache.rocketmq.remoting.netty.NettyRemotingClient.getAndCreateChannel(NettyRemotingClient.java:400) at org.apache.rocketmq.remoting.netty.NettyRemotingClient.invokeSync(NettyRemotingClient.java:369) at org.apache.rocketmq.client.impl.MQClientAPIImpl.getTopicRouteInfoFromNameServer(MQClientAPIImpl.java:1363) at org.apache.rocketmq.client.impl.MQClientAPIImpl.getTopicRouteInfoFromNameServer(MQClientAPIImpl.java:1353) at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:622) ... 10 more

但是消费者可以连接到代理，而rocketmq控制台可以显示状态。一切都很正常。 有人能帮忙解决这个问题吗？
