Not sure if there is a bug listed for this as yet.

@ChrisPotDev hi , it's been a while since your message, have you been able to find a solution?

I for one am using the current version of dsckeybusinterface and it is working fine with Mosquito 6.0.1 in Home Assistant. The only time I had issues was when I had not included the correct username/password in dsckeybusinterface for my mqtt broker.

@kghandi thank you for your answer question, what is the data that you filled in the configuration?
Broker: localhost or IP computer (raspberrypi)?
Port: ??

HomeAssistant running on a VirtualBox VM on a Mac.
Broker: core-mosquitto
Port: 1833

Broker config:

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

I use dscKeybusInterface example HomeAssistant-MQTT in which:
mqttServer is specified by IP address.
mqttUsername & mqttPassword are the same as those I use to log into home assistant.

Shifting this over to Discussions as it appears to be an issue with the HomeAssistant mosquitto component. One option is to check running the current release of Mosquitto as a separate service (current version: 2.0.14). I've tested with 2.0.11 and haven't run across this issue.
