MQTT - will not connect

[JornDL]

Hi

I'm trying to use MQTT with authorization log in, but connection is refused.

Could you please add the field "Client ID" to the MQTT authorization, please.

I'm using Mosquitto as my MQTT broker and it needs the "Client ID" to be abled to log in.

(great plugin - great work - happy with this)

I have mosquito too and Connect co without any problem

So what could be my issue ? I have a lot of other MQTT clients - all using Client ID - but here I get this error: [3/19/2023, 7:00:33 AM] [homebridge-melcloud-control] MQTT Connect error: Error: Connection refused: Not authorized

wrong credentials

[grzegorz914]

Check user and password

Just done that again to be sure and they are correct.

Also tried without the Prefix - but it makes no difference:

[3/19/2023, 7:19:17 AM] [homebridge-melcloud-control] MQTT Connect error: Error: Connection refused: Not authorized

[grzegorz914]

added in 0.10.1

That was super quick :-)

I just tried it, but it seems, that it uses another ID than the one I put in the config:

Config: "mqttClientId": "melcloud_2_mosquitto"

Mosquitto log: 1679208806: New connection from 127.0.0.1:47476 on port 1883. 1679208806: Client mqttjs_7b8e0617 disconnected, not authorised.

Homebridge log: [3/19/2023, 7:53:26 AM] [homebridge-melcloud-control] MQTT Connect error: Error: Connection refused: Not authorized

Mosquitto log - When I connect from my PC with MQTT explorer: 1679206392: New connection from 192.168.1.245:51471 on port 1883. 1679206392: New client connected from 192.168.1.245:51471 as mqtt-explorer-4286441e (p2, c1, k60, u'jorn').

I don't know if it makes any difference - but I'm running in a child bridge

[JornDL]

Also my zigbee2mqtt connection from the same RPi4:

1679187168: New connection from 127.0.0.1:33378 on port 1883. 1679187168: New client connected from 127.0.0.1:33378 as RPi4Main_zigbee2mqtt_2_mosquitto (p2, c1, k60, u'jorn').

[grzegorz914]

try again. 0.10.2

Just had breakfast - so a little later:

The log in still fails: [3/19/2023, 9:38:12 AM] [homebridge-melcloud-control] MQTT Connect error: Error: Connection refused: Not authorized

But It now uses the correct Client ID: Config: "mqttClientId": "melcloud_2_mosquitto"

Mosquitto log: 1679215092: New connection from 127.0.0.1:49278 on port 1883. 1679215092: Client melcloud_2_mosquitto disconnected, not authorised.

I can't what understand what is wrong - or what I'm doing wrong - mqqt section from config: "enableMqtt": true, "mqttDebug": false, "mqttHost": "127.0.0.1", "mqttClientId": "melcloud_2_mosquitto", "mqttPrefix": "melcloud/kitchen", "mqttAuth": true, "mqttUser": "jorn", "mqttPasswd": "****" The user/password is correct - also used in the same config for another plugin.

[grzegorz914]

May be try not use 127.0.0.1, set full address of mqtt server

[JornDL]

Tried that also without any luck

Strange, here all working correct, mosquito as broker on Mac. Check your broker authentication setting: https://mosquitto.org/documentation/authentication-methods/

[grzegorz914]

If your broker working only inside local network then you can allow unauthenticated access
