### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version pulsar client 3.01. pulsar broker 3.0.1 puslar proxy 3.0.1 ### Minimal reproduce step It is hard to reproduce ### What did you expect to see? When you use puslar client to create producer objects synchronously, you can trigger a timeout or other exception normally, rather than the thread staying stuck ### What did you see instead? Threads keep getting stuck when creating producer objects synchronously using puslar client. To reproduce it, the pulsar cluster is stopped, and a timeout exception is reported when the produce object is created. Therefore, it is not clear how this situation has arisen. At present, it has appeared many times in the production environment.  ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
