Kubernetes Traefik v2.3.0 - Web UI 404 Not Found after removing --api.insecure
Here's another take on the IngressRoute, adapted to your environment.
I think 99% of the issue is actual route matching, especially if you say --api.insecure works.Also as a rule of a thumb, logging & access log would help a lot in the DaemonSet definition.
