Mosquitto MQTT broker unable to connect to Home Assistant

Configuration
1

Hi all,

I recently installed HA operating system onto a mini PC. I then went ahead and installed mosquitto broker add-on and started the program; green dot shown. It was automatically dectected and shown in settings, integrations however when I click configure and submit I receive a message ‘failed to connect’.

  • Core 2023.11.1
  • Supervisor 2023.10.1
  • Operating System 11.1

I wonder if the issue is something to do with this statement - ‘Client disconnected due to protocol error’?

I’ve looked through many other posts but not able to get to the bottom of this. Appreciate any advice.

thanks
