Traefik 2.0 gate way timeouts - docker

Question

Created a simple Traefik instance with 2 services, only by http. I'm getting Gateway timeout in both instances, this is my only file where I created my services and traefik proxy.
version: '3.4'
services:
reverse-proxy:
image: traefik:2.0 # The official Traefik docker image
ports:
- "80:80" # The HTTP port
- "10553:8080" # The Web UI (enabled by --api)
volumes:
- /var/run/docker.sock:/var/run/docker.sock # So that Traefik can listen to the Docker events
networks:
- default
command:
- "--api.insecure=true"
- "--providers.docker=true"
- "--providers.docker.network=demo_swarm_network"
- "--providers.docker.exposedbydefault=false"
- "--providers.docker.swarmMode=true"
- "--entrypoints.web.address=:80"

The services are up and running, are so are the containers. Traefik is also running, just when I try to localhost:80/api/authentication or localhost:80/authentication I get gateway timeout.
Where is traefik sending my requests ? I've confirmed in the host ports, that the apps in both endpoints are running.
What's missing in my configuration ?

Huzzah! The timeouts disapeared when I updated the demo_swarm_network network to have overlay.
