can someone help please

Share full Traefik static and dynamic config, and docker-compose.yml if used.

Place 3 backticks in front and after code/config to make it more readable and preserve spacing.

Did you create a local.example.com domain or zone with the correct target IP?

Did you create the sub-domain with your DNS provider?
