Hassio-zigbee2mqtt: Could not connect to localhost mqtt server

[gualostly]

The error "not connected to mqtt server!" pops up whenever I set the server address to localhost or 127.0.0.1.
It works if I set it to the real intranet IP like 192.168.1.123.
Running on RPi3+ with mosquitto.
Any idea to make localhost works so it would still work after IP address change?

[danielwelch]

Are you using the official mosquitto add-on to run mosquitto? The community add-on? Or running it on another device altogether?

[gualostly]

Mosquitto was installed from Hass.io official addon, on the same machine. I only changed a few lines in the config, every other things were default settings.

My zigbee2mqtt config:
{
"data_path": "/share/zigbee2mqtt",
"homeassistant": true,
"permit_join": false,
"mqtt_base_topic": "zigbee2mqtt",
"mqtt_server": "mqtt://192.168.1.235:1883",
"serial_port": "/dev/ttyACM0",
"mqtt_user": "aaaaa",
"mqtt_pass": "bbbbb"
}
If I change the line to
"mqtt_server": "mqtt://127.0.0.1:1883",
Or
"mqtt_server": "mqtt://localhost:1883",
It does not work, tried removing the :1883 part, still no dice.

Mosquitto config:

{
"logins": [
{
"username": "aaaaa",
"password": "bbbbb"
}
],
"anonymous": false,
"customize": {
"active": false,
"folder": "mosquitto"
},
"certfile": "fullchain.pem",
"keyfile": "privkey.pem"
}

I wonder if there is any setting I could try? Thanks!

I use "mqtt_server": "mqtt://homeassistant:1883", although no idea how that works/resolves properly.. maybe the Os does have an entry that resolves that properly to the local machine.

[danielwelch]

Things should work with mqtt://homeassistant, assuming your port mapping is standard.

Hassio resolves this to the correct address behind the scenes.

Maybe you can try your broker name (if you use a custom broker). I had a custom broker name in my configuration.yaml file and tried using my local ip, my localhost and it wasn't working either.
Try it like: "mqtt://brokername:1883", (brokername = your broker name from your configuration file)

running hassio version 84.6 with Mosquitto plugin

confirmed

Although i should mention that resolving of this plugin is buggy; on any other plugin (or anywhere in the system/setup) I can either use 'hassio.local' or 'localhost'. (besides the 'homeassistant build-in name)*. This one does not support that; just fails on connection to MQTT server as mentioned in this issue.

* I do not have any (other) internal/local name resolving system in-place.

I am having the same issue. I've tried everything. I've tried everything. It appears to connect.

So the problem is if you change anything in the UI docker config it doesn't write properly to
/share/zigbee2mqtt/configuration.yaml properly. I had to edit it by hand via ssh.

I have also a problem with zigbe2mqtt. I installed the add-on and it worked. I could pair a device.
But after some upgrades of hassio (now 0.91.3), it is not working more. The log shows:

I tried a lot (with and without user and pass, different mqtt server adress), but all without success.
My config is:

{
"data_path": "/share/zigbee2mqtt",
"homeassistant": true,
"permit_join": false,
"mqtt_base_topic": "zigbee2mqtt",
"mqtt_server": "mqtt://homeassistant:1883",
"serial_port": "/dev/ttyACM0",
"devices": [],
"network_key": [],
"disable_led": true
}
and the configuration.yaml
mqtt:
broker: homeassistant
discovery: true

Can someone help me?

Mosquitto in hassio Docker network has alias core-mosquitto, so z2m's config has to look like this:

…
"mqtt": {
    "base_topic": "zigbee2mqtt",
    "server": "mqtt://core-mosquitto",
…
