Zigbee2mqtt won't start

I currently have a sonoff ZigBee dongle running ZHA. I purchased a second sonoff ZigBee dongle to run Z2M. I have followed several instructional videos and I can’t get it to run. It is giving me a repeated error of

Zigbee2MQTT:error 2022-12-18 10:24:53: MQTT error: Not supported!

Need a little help. Sorry, I’m still new and don’t know how to upload my code and log. At least from my phone

I you run the new 2 Sonoff dongle you need to add:

serial:
adapter: ezsp
port: >-

In your configuration.yaml file

Added that to my config file and now I get this

[10:52:30] INFO: Preparing to start…
[10:52:30] INFO: Socat not enabled
[10:52:31] INFO: Starting Zigbee2MQTT…

Zigbee2MQTT:info 2022-12-18 10:52:32: Starting zigbee-herdsman (0.14.76)

It’s been like that for 10+ min and in my MQTT log it now shows this on repeat

2022-12-18 10:30:03: New connection from 172.30.32.2:37304 on port 1883.
2022-12-18 10:30:03: Client closed its connection.

It looks like that Z2M can not connect to your MQTT server.
Did you use the right username and passwd?
Did you install a MQTT broker anyway?

Password is correct and I have mosquito MQTT installed and running

Which Sonoff adapter? They’ve sold at least half a dozen different ones, including two different (and incompatible) models of the Plus - one with CC2652 inside and one with EZSP inside.

I’d also check that the details for MQTT you gave Z2M work in a tool like MQTT Explorer

I finally got it running. A friend came over and help me with it. I guess setup is a bit different with HA generic then what I was seeing in setup videos

What was the problem?

I’m running HA generic 86. I guess the setup instructions I was following where incorrect and not for my OS
