After Enabling VIPChannel, the 4.x Client Encounters an Exception When Connecting to the Cluster: "org.apache.rocketmq.remoting.exception.RemotingConnectException"
After the client enables VIPChannel, the SDK establishes a connection with a designated port on the Broker for message transmission. However, this feature is not applicable to cloud-based clusters. Enabling it may cause errors such as connection failures. If encountered, disable this feature during initialization:
producer.setVipChannelEnabled(false);
consumer.setVipChannelEnabled(false);
