How to fix Paho-MQTT result code 5

When you see result code¬†5 in paho-mqtt this means Unauthorized! Typically it means you don’t have the correct username and password set.

Set username & password using

client.username_pw_set("myusername", "aeNg8aibai0oiloo7xiad1iaju1uch")

Example of how to connect with username & password:

client = mqtt.Client("mqtt-test") # client ID "mqtt-test"
client.on_connect = on_connect
client.on_message = on_message
client.username_pw_set("myusername", "aeNg8aibai0oiloo7xiad1iaju1uch")
client.connect('127.0.0.1', 1883)
client.loop_forever()  # Start networking daemon
