   Could  you provide more information for troubleshooting? e.g. the version of 
`RocketMQ Name Server` / `Broker` / `Dashboard`, the configuration you use.
   
   `Query by message id` and `query by message topic` use different methods.
   
   `Query by message id` : parse the message id into `broker address` and 
`physical offset`, then retrieve message directly.
   `Query by message topic`: retrieve router info (message queue) by topic form 
the name server then pull message from broker.
   
   
   According to my preliminary judgment, if seems the query name server router 
info request has problem, not sure whether your nameserver configuration is 
correct or not, maybe you have to check how you create your topic too.
   ```java
   TopicRouteData topicRouteData = 
this.mQClientFactory.getMQClientAPIImpl().getTopicRouteInfoFromNameServer(topic,
 timeoutMillis);
   ```
