aliasHeadersStrategy breaks 'traefik healthcheck --ping'

What did you do?

after adding to container env

    environment:
      TRAEFIK_ENTRYPOINTS_TRAEFIK_HTTP_ALIASHEADERSSTRATEGY: keep (reject or delete)

my container (I'm using one from the dhi.io) with healthcheck section:

    healthcheck:
      interval: 1m
      retries: '5'
      start_period: 30s
      test: ["CMD", "traefik", "healthcheck", "--ping"]
      timeout: 10s

unable to reach "healthy" state, manual run of healthcheck test is also failing:

# docker exec -it traefik traefik healthcheck --ping
Error calling healthcheck: Head "http://:8080/ping": dial tcp :8080: connect: connection refused

I tried with keep/reject/delete for TRAEFIK_ENTRYPOINTS_TRAEFIK_HTTP_ALIASHEADERSSTRATEGY, but container is always goes to "unhealthy". The only fix is to remove TRAEFIK_ENTRYPOINTS_TRAEFIK_HTTP_ALIASHEADERSSTRATEGY

What did you see instead?

NAMES              STATUS
traefik            Up 4 minutes (health: unhealthy)

What version of Traefik are you using?
