Keep getting "Connection refused: Not Authorized" error

[ccuono]

Hello,

My MQTT server uses username/password authentication; I set the username and password values in the config yaml and still keep getting this error. Here is some print out from journalctl:

Beginning of config.yml looks like:

mqtt:
    # Specify your MQTT Broker's hostname or IP address here
    host: 192.168.45.120
    port: 1883
    #leave empty if none
    username: mosquitto_user
    password: fakePAsS}},,,222
    # Preface for the topics $PREFACE/$TOPIC
    preface: dash

And here is some version details about what I'm running for my mqtt server:

mosquitto version 1.4.14 (build date 2017-10-21 18:07:04+0200)

mosquitto is an MQTT v3.1.1/v3.1 broker.

I was able to produce some log output from my mqtt server, here are some more details:

1525661121: New connection from 192.168.82.120 on port 1883.
1525661121: Socket error on client <unknown>, disconnecting.

1525661131: New client connected from 192.168.82.221 as DVES_3C1F00 (c1, k15, u'mosquitto_user').

The first item in the output is when I attempt to spin up the daemon - I get the same error but it looks like the mqtt server is kicking it out because of some socket error?

Hmm, strange. Under the hood I just use this library: https://www.npmjs.com/package/mqtt#client

I would add some debugging, make sure your complex password is being read correctly. Also, it might be a port/protocol problem. By default I think it uses mqtt protocol.

@stjohnjohnson thanks. the port hint helped
