No route to host with docker swarm

I would like to use the harbor solution with traefik in front but with version 2.0 of traefik.
I can not reach the harbor nginx service. In version 1.7 everything worked perfectly ... When I look at the traefik logs, there is a no route to host to the nginx container.

Could someone help me ?


Could you provide more information about your configuration?

Thanks tou for your reply, I have found my mistakes.
I have forgot to include traefik network in my other harbor.yml ...
