New install with errors.

[Dave21w]

I'm not sure what I'm missing here, I've installed Domoticz lots of times using the Easy option and never had an issue. The install goes smoothly with no error and completes telling me the IP and ports available however I get this error in the log.

I can still connect to Domoticz on both the ports and I probably wouldn't have noticed the error yet except I also have zigbee2mqtt and mosquitto installed running perfectly (i can see the devices in mqtt explorer) however after adding MQTT Auto Discovery with LAN interface to my hardware I see no devices in Domoticz (yes I have Add new hardware devices enabled) so was checking the log for errors.

Any ideas ?

On the picture you showed there are no errors. Errors are in the Error Tab.
Is in Zigbee2MQTT the Home Assistant integration enabled?

On the picture you showed there are no errors.

It's not so obvious as that's screen capture (not needed & cumbersome, as that's 100% text) but there is indeed some web server errors logged (host not found + address being "::"). So if there is some network related issues this may affect MQTT etc...

[Kedi]

As I see it, it is about IPv6. IPv4 works as it should and the Domoticz GUI is accesseble on both ports.
So should MQTT work on IPv4.

You are correct however I do not have an error tab, only all and status, the screen grab was from the all tab. I never noticed the error tab was missing however I have now after doing a few tests found something else which is also strange. If I point the MQTT Auto Disc on the new Domoticz install to a different IP where I have another instance of Domoticz and Mosquitto then it imports the devices which means apart from the strange IP issue at boot the device auto discovery is working.
This means there must be an issue with the Mosquitto instance on the new install but then I also know its running as zigbee2mqtt is working and I can see the devices in the new instance using MQTT explorer so now I'm even more confused !!

Error tab is only present if there are errors.
Check the differences between the 2 mosquitto services.
Especially the contents of /etc/mosquitto/mosquitto.conf and other included files.
There might a difference, look for "allow_anonymous true"
Otherwise put full debugging on the mosquitto service by putting temporarely

Code: Select all

persistence true
persistence_location /var/log
log_dest file /var/log/mosquitto.log
log_type all

in the mosquitto.conf file
In that log file should be a hint what is wrong.

Thanks @Kedi I'll give that a go a bit later this morning. Luckily for me my Domoticz - Zigbee test pi is at work which is where I was building the new install for my friend on another 3b+
