Hello everybody,
I'm trying to implement username / password authentication and ACLs
I received the rc05 error message connecting from ESP8266 and MQTT-Spy (Windows).

I try this from lab-raspi ... it works.
Raspi uses mosquitto 1.5.7.
After upgrading raspi to mosquitto 1.6.12 i got error and RC=5 too.

I try to find something within change-log ... without success.
Does someone have a hint for me?
Thanks in advance.
Dirk

The MQTT v3.1.1 CONNACK return code value 5 means "not authorised". It suggests you have the incorrect username/password. It's difficult to say any more without knowing more details of your setup. I would suggest trying with mosquitto_pub and mosquitto_sub first, they are probably easier to figure out rather than relying on getting the other code correct.
