Addon does not work if HA itself is HTTPS

Add a flag if HA is https or not, how hard can it be?

I've had this configured for years. I have had HSTS preloaded for years too, so not gonna be removing this.

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 172.30.0.0/16
    - XXXX:XXXX:XXXX:XXXX::/64
    - XXX.XXX.XXX.0/24
  ssl_certificate: "/ssl/fullchain.pem"
  ssl_key: "/ssl/privkey.pem"
  ssl_profile: "modern"

I would guess intermediate?

In my case, I use a self signed certificate for my internal network and nginx simply cannot verify the authenticity of that certificate. You could set proxy_ssl_verify to off, but that would defeat the point. Adding a custom proxy_ssl_trusted_certificate is a 3-years old feature request: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/2271
