My add-on Mosquitto broker is not accessible from outside of the home assistant server. Connection between Home assistant mqtt integration and the mosquito broker works. When I listen int he broker I can see messages between HA and broker. I also installed MQTT Explore as add-on in HA and this connection is also established and I can see messages going between those. But from the MQTT Explorer application on my Mac it is not possible to make a connection to the mosquito broker. I used the same credentials for all the clients (I made a special user for this in HA). Does anybody have any idea what could be wrong?
Hello reinder,
What IP address are you using to connect?
Thank you for your reaching out. Yesterday night I was able to solve it.
First I used not an IP address but the host name: core-mosquitto. Later I added the port to this name core-mosquitto:1883. But no luck
Yesterday I tried the IP address with port number: 192.168.1.113:1883 and that did the trick. I still don’t understand what was wrong with the host name because I could make a connection with the MQTT Explores as add-on on HA.
