Quick Tip #2 (Mosquitto ACL)

If setting up a new instance of Mosquitto and the instructions (or someone) tells you to add an ACL file, do yourself a favor and ignore them…at least initially. I just came across this and an ACL file can cost you days of troubleshooting.

Once you have your services communicating over MQTT, then go ahead an add an ACL file to your Mosquitto instance, but add a single user at a time and restart the services to make sure everything still functions as expected.
