Traefik 2.1 and docker-compose over https

The issue i am facing is that the application (Laravel) creates urls f.e. for paginated responses. To do so it gets the URL Scheme from the request. However it does so by f.e. relying on the $_Server variables generated from the request.

as the traefik -> nginx is done over port 80/ http, the $_Server['HTTPS]' is false/not present

One way i think of overcome this, is securing the traefik->nginx communication ... is that possible with traefik?
