Cannot get smartthings_mqtt_bridge server to run

I’m trying to mqtt bridge setup, but I cant seem to get the smartthings mqtt bridge server to run. For my output, it only goes so far as to say Connecting to and it hangs

homeassistant@raspberrypi:~/.homeassistant $ smartthings-mqtt-bridge
info: Starting SmartThings MQTT Bridge - v2.0.0
info: Loading configuration
info: Loading previous state
info: Perfoming configuration migration
info: Saving current state
info: Connecting to MQTT at 192.168.86.20:8080

Here is my config.yml:
mqtt:
host: 192.168.86.20:8080
preface: smartthings
username: homeassistant
password: xxxxxxx

Port number to listen on

port: 8080

Any help would be appreciated

I’m running v1.4.0 so may be different now, but I don’t think 8080 goes with the
mqtt host address, so try

host: 192.168.86.20

That’s for the reply, but that didn’t work either. What username/password are you using? I’m wondering if that’s my problem.

That would be the username and password that was configured for your mqtt broker.
If you use mosquitto, use (fill in BROKERNAME with the one you want):

sudo mosquitto_passwd -c /etc/mosquitto/pwfile BROKERUSERNAME

and this prompts for a password.

I’ve been seeing “mosquito” in a lot of posts. Pardon my ignorance, but what is mosquito? Should I be using it? I’ve only got about 3 days experience with Raspbian.

mosquitto is an implementation of a MQTT Broker.
If you don’t have an MQTT Broker, you will need to set one up.

So “smartthings-mqtt-bridge” is not a a broker? Sounds like you found my problem.
