Thank you!

host.docker.internal only exists when using Docker Desktop.

what host should be used for docker host?

The doc you mentioned has all the examples using the Docker socket (unix:///var/run/docker.sock). Why would you change to IP address?

Compare to simple Traefik Swarm example. Note it’s old v2 config with providers.docker, which is now providers.swarm.

but I confirm after changing it to default value, fixed my issue)

thank you so much!
