Hey Guys,
i've got a problem with Traefik 2.x in Docker Swarm :(.
First of all (and for learning purposes) i followed this guide:
Everything worked pretty fine with a single node (tried at home and with a DigitalOcean droplet), also with the Google Oauth and/or Auphelia.
Because i like that guide and configuration, i wanted to use it also within a docker swarm, but it doesn't work as expected.
The container is up and ok, but when i access the dashboard, i always get a 404 Error.
I tried some things i found on github and stackoverflow, but they did not work.
Could you please help me to get this thing working?
version: "3.8"

And because i use a .env file, i deploy the stack with this command:
docker stack deploy -c <(docker-compose config) traefik
It's working fine, the traefik container is only on my manager node, but that's it^^
Would be really nice 
Greetings
