Website serves content over HTTP not HTTPS

[Kyle-Jeynes]

Describe the bug
Because the service is exposed to port 80, Laravel picks up the request as HTTP although all information was passed over HTTPS.

To Reproduce
Steps to reproduce the behavior:

1. Deploy your Laravel VCS that uses url()

Expected behavior
url()->to('/') should return HTTPS not HTTP.

To fix this issue

Append the following into your app/Providers/AppServiceProvider.php and ensure your laravel/src/.env is in production.

public function register() {
    if (env('APP_ENV') === 'production') {
        $this->app['request']->server->set('HTTPS', true);
    }
}

We'll look into trying to provide a fix via Traefik but the above will work in all cases.
