Connection to InfluxDB fails

Hi mates,
Hope you are all doing good, I am taking some time to work on my home assistant project and have few problem setting up influxdb.

I am following this tutorial as it seems to be the best I could find, adapting it with my project.

My problem is HA is not talking to influxdb though Grafana can see it and communicate with it. Of course I cannot make any useful chart as HA is not filling influxdb with my sensors data.
I have HA, Influxdb, Grafana (and Node-red, Deconz) install using docker. I am not using Hassio

cat Home_Assistant/.HA_VERSION 
0.106.6

At startup, I can see in the HA logs the influxdb service is starting but fails to connect :

Retrying again in 60 seconds.

The last line makes me think home assistant is trying to use the deprecated webui to connect but I am not so sure.
My HA config.yaml :

influxdb:
  host: 192.168.1.253
  port: 8086
  database: home_assistant
  max_retries: 10
  include:
    entities:
       # Batteries
       - sensor.bout1_salon_xiaomi_battery_level
       - sensor.bout5_salon_ikea_battery_level
       - sensor.temp_salon_battery_level 
       # Temperatures
       - sensor.temp_salon
       # Humidite
       - sensor.humid_salon
       # Pression
       - sensor.press_salon 

I can access the databased through command line of course and Grafana but not HA.
What could be wrong ?

Just in case, my docker-compose file :

version: '3'
services:

  homeassistant:
    container_name: home-assistant

    restart: always
    ports:

    volumes:

Any idea on what could be wrong ?
I was planning on writing a French tutorial on HA installation and all but I think I am not auite ready as I cannot figure out this problem on my own…
Cheers,
