We see here that in the in cluster setup, Headlamp does not support TLS termination at the container. TLS is terminated at the NGINX ingress. This creates issues for users who want to use NGINX TLS passthrough and transport server with the intent that TLS is terminated at the Headlamp container and not before that. If this feature is included as an option to the current code base itll help both sets of users.
