Create an reverse proxy with Traefik from a certain endpoint onto a local network port

Question

I'm trying to do a reverse proxy with Traefik, like Nginx. To resume, I would like a proxies requests from a certain endpoint onto a local network port, that happens to be a SSH tunnel with Traefik.

Actually it works with Nginx but Would like to stop using Nginx instead of Traefik.

I already test some configs but the Home Assistant Add-on (Autossh) doesn't connect to it. (It works like a charm with Nginx in the same server).

Here, my Traefik configuration :

docker-compose.yml

version: '3.7'

services:
  reverse-proxy:
    restart: always
    image: traefik:chevrotin
    ports:
    - "443:443"
    - "80:80"
    volumes:
    - /srv/traefik.toml:/etc/traefik/traefik.toml
    - /srv/services.toml:/etc/traefik/services.toml
    - /var/run/docker.sock:/var/run/docker.sock
    - /srv/acme.json:/acme.json
    labels:
    - "traefik.http.routers.api.rule=Host(`dashboard.domain.com`)"
    - "traefik.http.routers.api.service=api@internal"
    - "traefik.http.routers.api.entrypoints=http"

    - traefik.http.routers.nas.entrypoints=https
    - traefik.http.routers.nas.rule=Host(`home-assistant.domain.com`)
    - traefik.http.routers.nas.service=nas@file
    - traefik.http.routers.nas.tls=true
    - traefik.http.routers.nas.tls.certresolver=letsencrypt
