Pentair Screenlogic MQTT issue?

Continuing the discussion from [New Addon] Pentair Screenlogic:

This is my config for MQTT Broker:

logins: []
anonymous: false
customize:
active: false
folder: mosquitto
certfile: fullchain.pem
keyfile: privkey.pem
require_certificate: false

This is my config for pentair:

MQTT_server: 127.0.0.1
MQTT_port: ‘1883’
MQTT_user: mqtt
MQTT_password: mqtt
ScreenLogic_server: 192.168.2.21

I created a user: username: mqtt, password: mqtt

Is there something else I should be adding somewhere?
