Having trouble setting up MQTT

Hello,
I am trying to get started with MQTT in Home Assistant, but I am running into trouble. So far I have:

1. Installed the Mosquitto MQTT broker add-on
2. Set up a new user called “mqttuser”
3. Flashed Tasmota on a 3-relay light switch
4. Configured MQTT in Tasmota

It seems like it is connecting to Home Assistant, but auto discovery is not working and neither is manually creating a switch entity in the config file.
MQTT Add-On Log:

MQTT Configuration:

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

Tasmota Console (while attempting manual config):

Any ideas what I’m doing wrong?
