Laravel not using https for assets and dynamic routes
The asset() helper relies on a couple possibilities to determine whether to make a HTTP or HTTPS URL:
$_SERVER['HTTPS']beingon. This is Apache's way of doing things. For nginx, you can set that server param yourself in the config.$_SERVER['HTTP_X_FORWARDED_PROTO']beinghttps.
If you're behind a load balancer, it's probably sending the X-Forwarded-Proto header, but Laravel doesn't trust it by default because it can be set by a malicious user in some cases. You can tell Laravel to trust this header coming from your load balancer using the TrustedProxy package. (edit: This is now built into Laravel)
