Can't get MQTT to work.

[PeJeWe]

I'm starting with MQTT and want to use it with esp8266 devices
i can't get it to work.
what's working now:
i can send local messages to domoticz (mosquitto_pub -h localhost -m '{ "idx" : 1, "nvalue" : 0, "svalue" : "25.0" }' -t 'domoticz/in')
I can''t get it to work from outside the localhost (domoticz RPI3b+)
my mosquitto config file looks like this:

Code: Select all

# Place your local configuration in /etc/mosquitto/conf.d/
#
# A full description of the configuration file is at
# /usr/share/doc/mosquitto/examples/mosquitto.conf.example

per_listener_settings true

pid_file /run/mosquitto/mosquitto.pid

persistence true
persistence_location /var/lib/mosquitto/

log_dest file /var/log/mosquitto/mosquitto.log

include_dir /etc/mosquitto/conf.d
allow_anonymous false
listener 1883
password_file /etc/mosquitto/passwd

and is located at /etc/mosquitto/mosquitto.conf
i use the firewall ufw and have set the port 1883 open for traffic ipv4 and ipv6 (with the firewall disabled it is not working either)
when i want to connect to my broker from a windows pc with MQTT explorer it keeps disconnecting.

I have set a mqtt username with password.
anonymouse or with user/password login it won't let me login externally.
i use a normal IP range like (192.168.1.1 to 192.168.1.254)

Has anyone of you guys tips/tricks?

Did you try without the user/password setup?
Try with log_type all or log_type_debug in the mosquitto config file.
Is there a config file in /etc/mosquitto/conf.d directory that could prevent anything?

After a complete reinstall of domoticz and its components and mosquito.
I have not found te reason where it went wrong what was blocking the network connections.
I now have it running , and also I can connect mqtt explorer.
Only without tls.
Now I have to work it out how I can simple send data to/from domoticz.
