Redelivery unacked messages

MQTT
1

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
