Double-take configuration

I am running home assistant with add-ons double-take, deepstack and frigate-proxy.
Frigate is running on an independant container (works well, streams and detects persons).

What I am not able to setup is double-take to help on face recognition incl training

Even a simple config results errors:
config:

mqtt:
  host: homeassistant.fritz.box
  port: 1883
  user: mqtt
  password: 'myPW'
  client_id: doubletake

frigate:
  url: http://docker2.fritz.box:5000

detectors:
  deepstack:
    url: http://homeassistant.fritz.box:5001

In status it shows
double-take: green
mqtt: red “reconnecting” - LOG: error: MQTT: offline - warn: MQTT: reconnecting
frigate: green
deep-stack: red “connect EHOSTUNREACH 192.168.178.235:5001”

I have no idea why MQTT is offline!
I have no idea why the config is using 192.168.178.235 which is not the IP of my deep-stack

any ideas?

Greetings master,

I found it is not good to assume anything, so do you have an MQTT Add-On also installed and running? That would also be required and

That could be interpreted as it cannot find the MQTT Broker.

Oh @Sir_Goodenough - sorry for not having been clear on that.
yes, I am having Moquitto running with 48 devices.
I, unfortunately, cannot see the “frigate”-device in Homeassistant, but see it on my windows “mqtt explorer”
grafik

that is the reason why I have ZERO idea why I get “offline” and “reconnect” in double-take…

At this point then I would make sure the one that is not wanting to log in has the right login info or maybe add a login-password to the Mosquitto Add-On config just for that thing so you can see it log-in easier and chase the trace easier.
