Cannot connect my iPhone Home Assitant App anymore : Shared.WebhookError 3

Hi,
For some reasons (?), my iOS Home Assistant App doesn’t want to connect my Home Assistant Web App anymore. I get the error : Shared.WebhookError 3

Here is my setup :
Home Assistant is deployed on my local server using docker-compose :

version: "3"
services:
  homeassistant:
    container_name: homeassistant
    restart: always
    image: homeassistant/home-assistant:latest
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ./ha/config:/config
    ports:
      - 8123:8123
    networks:
      - default
      - traefik
    labels:
    - traefik.enable=true
    - traefik.docker.network=traefik
    - traefik.http.middlewares.ha-force-tls.redirectscheme.scheme=https
    - traefik.http.routers.ha.rule=Host(`ha.mywebsite.com`)
    - traefik.http.routers.ha.middlewares=ha-force-tls@docker


    - traefik.http.routers.ha-tls.rule=Host(`ha.mywebsite.com`)
    - traefik.http.routers.ha-tls.tls=true
    - traefik.http.routers.ha-tls.tls.certresolver=acme-production


networks:
  default:
  traefik:
    external: true

My ./ha/configuration/configurations.yml is :

default_config:


homeassistant:
  customize: !include customize.yaml

# Text to speech

  trusted_proxies:
   - 192.168.80.3 #Traefik container IP

the log I see when I get the error in the home-assistant.log is :

Does anyone have an idea on how I can solve this ?
For information, the access using my laptop is working using the same credentials and URL…
thanks for your support!
