Mosquitto Setup Troubles

Hi All,

I’m having no end to trouble with Mosquitto, I’ve installed the addon so that I can set up bluetooth monitor. This is what I’ve done so far:

Addon config:

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

I disabled ports 1883 and 1884 as recommended by clearing the text next to them.

I connected via SMB to create /share/mosquitto/acl.conf and accesscontrollist they look like this:

acl_file /share/mosquitto/accesscontrollist
user mqtt
topic readwrite #

I’ve created a user called mqtt in homeassistant (config > users > add)
I’ve added the mqtt integration (config > integrations) and when it asked if I wanted to use mosquitto I said yes and enabled discovery.

Unfortunately I don’t think any of it works:
Going to dev tools > mqtt and listening to # I see nothing. Even when I publish with the tool above.
Adding the mqtt-in shape to node-red it permanently reports “connecting”
I can see the monitor script publishing messages but nothing seems to come of them.

I’m not sure what I can look at yet. All the guides get to this point and it all just works.
