@franciscoj: Thanks for sharing your config files.
For others, please make sure to fix the typo in line 19 of traefik.config.toml before using:
change [http.services.my-ap.loadBalancer] to [http.services.my-app.loadBalancer], otherwise search and replace would'nt find this occurrence.

Thanks for the comment, I just fixed it :)
