Force https on traefik with docker-compose, mixed content

Traefik Traefik v2
3

Yes i enabled the redirect and that works. But only of the initial request. The web-app behind traefik thinks the request is a http request. So it tries to serve all assets with http, so i get a lot of mix content error's(like this

)

i found a workaround for laravel and for wordpress
as exaple the wordpress workaround:

if ( isset( $_SERVER['HTTP_X_FORWARDED_PROTO'] ) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')
$_SERVER['HTTPS']='on';
$http_s = ( !empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') ? 'https' : 'http';

I don't had this problem virtual servers with nginx.
