   ### Runtime platform environment
   
   windows11
   
   ### RocketMQ version
   
   5.3.1
   
   ### JDK Version
   
   1.8
   
   ### Describe the Bug
   
   本地部署了两个local proxy，proxy1,proxy2，当作两个分片，其中proxy1创建topic: 
1a，另外一个proxy2创建topic: 2b，客户端地址配置两个proxy的地址，写其中一个topic，比如 1a 
，可能会失败，当请求到的proxy2的时候，客户端会报错，获取topicroute失败，导致无法发送消息。
   
   ### Steps to Reproduce

   ### What Did You Expect to See?
   
   正常应该能获取到topicRoute，因为proxy获取路由是从nameserver获取的。
   
   ### What Did You See Instead?
   
   客户端获取路由失败，终止发送消息。
   
   ### Additional Context
