Traefik v2 terminate TLS at AWS ELB does not work

Traefik Traefik v2
1

It seems that I am unable to make TLS termination at the AWS ELB work with traefik 2. If I configure the load balancer backend to be https and give tls information to the dashboard ingress, everything works fine.
If I use the definitions below with the http backend and no tls information on the ingress route, the Dashboard (or any other ingressroute I create) gives a 404 on any of its paths.

Traefik version is 2.4.7.

Any suggestions and/or explanations are appreciated.

Thanks,
Nick

SOLVED - I had overlooked that tls was enabled on the traefik pod websecure port. :man_facepalming:
