Traefik cannot access Dashboard - traefik

Question

I have a problem with Traefik. All my services are OK, Traefik does his job, retrieves the certificates of Lets Encrypt, makes Load blancing between my different applications.
My problem is that I can't access the Dashboard, it asks me a login/password, yet I informed it in the docker-compose.
version: "3.7"
services:
traefik:
image: traefik:chevrotin
command:
--entrypoints.http.address=:80
--entrypoints.https.address=:443
--providers.docker=true
--api=true
--certificatesresolvers.letsencrypt.acme.httpchallenge=true
--certificatesresolvers.letsencrypt.acme.httpchallenge.entrypoint=http
--certificatesresolvers.letsencrypt.acme.email=mymail#mail.com
--certificatesresolvers.letsencrypt.acme.storage=/letsencrypt/acme.json
labels:
- traefik.enable=true
# Redirect all HTTP traffic to HTTPS
- traefik.http.routers.to-https.rule=Host(`traefik.mydomain.com`)
- traefik.http.routers.to-https.entrypoints=http
- traefik.http.routers.to-https.middlewares=to-https
- traefik.http.routers.traefik.rule=Host(`traefik.mydomain.com`)
- traefik.http.routers.traefik.entrypoints=http
- traefik.http.routers.traefik.middlewares=auth
- traefik.http.routers.traefik.service=api#internal
- traefik.http.routers.traefik.tls=true
- traefik.http.routers.traefik.tls.certresolver=letsencrypt
- traefik.http.middlewares.to-https.redirectscheme.scheme=https
- traefik.http.middlewares.auth.basicauth.users=MyLogin:MyPassword
ports:
- 80:80
- 443:443
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
- /docker/letsencrypt:/letsencrypt
if you have a idea. Thanks

I find. I'm not encoded my password.
I use this website : https://www.web2generators.com/apache-tools/htpasswd-generator
to encoded my password.
