Hi,
I've been trying to poc on a docker swarm traefik on a docker swarm cluster.
traefik : 1.7.12/maroilles (miam)
docker 18.09.7-0ubuntu1~19.04.4
here are my stacks

as you can see, the check is on /jyc on the apache stack.
on one of the three httpd instances, i've created a simple jyc file.
so only one instance ca reply a 200/OK response to the healthcheck.
you'll see that : a curl on the traefik always respond 200.
you'll see in the logs that 2 of the instances doies not respond 200, but 404.
but, on the dashboard, on the backend list, i still got three servers.
i would have expected to have only one server in the backend list.
