IOT2050 - Node-red to Adafruit (MQQT not connecting)

[davidstuart97]

Hi,

I'm in need of assistance in resolving why I can't connect to Adafruit through Node-RED. I've successfully connected to Adafruit using the same flows on Node-RED from another computer.

On my IOT2050 device:

Node-RED is operational, successfully retrieving data from a PLC.
Mosquitto: I've added a listener and checked its status, which seems okay.
However, I keep encountering this error message: '26 Feb 18:15:29 - [info] [mqtt-broker:Adafruit] Connection failed to broker: mqtt://io.adafruit.com:1883'

The password and username for Adafruit is correct as used on another computer.

What could I be missing?

Can you do telnet io.adafruit.com 1883 on the IOT2050, i.e. reach that broker at all via its Internet connection?

I've tried this:-

Hello, check your internet connection.
If you use the 2 ethernet port you can check the box "Never use this network for default route" into iot2050setup / Networking / Edit a connection / "your network interface"
Reboot

Hi rFord,

On initial Setup I changed the network address to give access to the unit. I've managed to connect the unit by using Mobaxterm (like putty) and have established a connection. I also changed the default port address and still I can't seem to connect with Adafruit using Mqqt protcol.

I've ordered up a UART to usb but will keep looking for a solution.
Thanks for your support

It looks like I have an issue with mosquito as it will only operate locally. see below: -
I have followed the above that was discussed but still not getting joy. Please can someone assist
Please see configuration below :-
Mosquitto.config

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

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

listener 1883
allow_anonymous true

Reboot IOT2050:-
root@iot2050-dave://etc/mosquitto# mosquitto

1710843904: Using default config.
1710843904: Starting in local only mode. Connections will only be possible from clients running on this machine.
1710843904: Create a configuration file which defines a listener to allow remote access.
1710843904: For more details see https://mosquitto.org/documentation/authentication-methods/

1710843904: Opening ipv6 listen socket on port 1883.
1710843904: mosquitto version 2.0.11 running

I've added : -
listener 1883
allowed anonymous

But it still doesn't connect
