mtt broker I used is Emqx4.2.2, I did not find error message in emqx error log. Is this a hivemq client problem or emqx problem? what should I do to find solutions?

hivemq client version is 1.2.2

Hi @HiwayChe as you call a blocking operation (CompletableFuture.get()), your current thread is blocked until the operation completes. The publish operation completes if the client receives the acknowledgement packet from the server.

what should I do to find solutions?

I would suggest looking at which packets are sent/received. For example you could use Wireshark on the same machine where the client is running on and filter for mqtt.

Hi @HiwayChe - since this issue has gone stale could you let us know if it's still an issue for you? We've had quite a few releases since then. If it is, could you try it with the latest version of the client?

Thanks - let us know. We'd be more than happy to pick up the investigation on this.
