Hi HiveMQ team,
Prerequisites:
go paho client - 3.1.1
hivemq - 4.9.0
In my subscriber I have a logic that requires to either ack or nack received message from the broker according to some reasons. In case when message isn’t acked I assume to receive that message again from the broker in some time. nevertheless it doesn’t happen.
as I understood from mqtt spec it’s possible.
be kind to explain me if missed something

Hi @Anton ,
Great that you are interested in MQTT and HiveMQ, welcome to the community!
In order to understand what your issue is, we need some additional information from you:
What is QoS that you use for your message? Can you share a link to the source code of your client?
Thank you,
Kind regards,
Dasha from HiveMQ Team
