Hi,
I have openhabian on my raspberry PI4. I have the MQTT Thing offline. I install MOSQUITTO via the openhabian-config tool.
If I choose no password the system works. If I set a password don’t works.
I want to avoid to use the MQTT without the password. I read all the other 21 posts with similar problrem in the comunity but unfortunally I didn’t find the solution. I tryed to reinstall mosquitto, chenge use, reset password, try different password, reboot the raspebby.
Sorry if that came across rudely, as I didn’t mean for that to be the case. There have been times when I’ve assumed someone has done something, and it turns out that they missed it. I’ve also been guilty of overlooking something simple steps. So when it’s not directly stated, it’s always worth asking the question. What’s obvious to you and me may not be obvious to someone else.
I would try using MQTT Explorer to connect to the broker with the password set up. That will at least tell you that the broker/password is working properly.
You use port 8883 instead of port 1883 because you would like to use encrypted connection ?
What does the mosquitto.log in /var/log/mosquitto show ? Any verbose error message that helps to identify the root cause ?
I think yes that 8883 is the port for use encripted connection.
@rpwong with MQTT explorer I think is the same…without password works and with password no.
I put also the last row of the log… I don’t know if is normal or not…

@Wolfgang_S yes mosquitto.conf contain allow_anonymous false.
Sorry I don’t undestrand what’s wrong? And why with MQTT explorer if I don’t put the password the connection is not allowed but in openhab yes :)?
ok…now works…
I change the listener in the mosquitto.conf from 1883 to 8883 and also disable safety connection and also disable select certificate. Now with the wrong password don’t work and with the correct password work.
Don’t ask me why this settings of selectors I just try and error but maybe someone expert of the MQTT protocol can clarify
Thank a lot @Wolfgang_S@rpwong that you help me for the resolution!
Regards
