MQTT issues/questions

I have some issues with MQTT Mosquitto broker and a client (Currently One) .
I can se the message in mqtt explorer and in incomming mqtt.

2024-07-09 10:31:41: Received PUBLISH from one_8115_841bf40cdadc (d0, q0, r0, m0, ‘currently/one/841bf40cdadc/progress’, … (70 bytes))

Should i use 3.1 or 5 for the protocol?
Does anyone know what this message is ?

2024-07-09 10:26:01.850 DEBUG (MainThread) [homeassistant.components.mqtt.client] register write 71
2024-07-09 10:26:01.852 DEBUG (MainThread) [homeassistant.components.mqtt.client] unregister write 71

What issues? What are you trying to do and what is happening?

Don’t get bogged down in protocol versions and debug messages until you know what the problem is.

My sensors is not updating, tried to remove etc.
discovery works fine but updating is not working.

Troubleshooting MQTT? MQTT-Explorer can help you be successful!

If you have Addons available, try adding this Addon repository to your Addon list. GitHub - GollumDom/addon-repository.

Will try that, from the looks of it, im recieving ping.

But according to MQTT Explorer its “stucked” ? in retained.
