Squid Reverse Proxy - Redirect to https does not work

[BerndHu]

Hello,

I use the squid Pakage (Version 0.5.3, on PFSense 2.8.1) as Reverse Proxy and acme for Lets Encrypt. I setup a Nextcloud behind pfsense, everything works well. If i enter http://cloud.example.org I came to https://.... without a SSL-error. That works, because Nextcloud switch himself to https. Now I install Vaultwarden, this side is only available with http. If I enter the URL from Vaultwarden with https:// ... everything works, but If I enter just vaultwarden.example.org in the Browser, there is no switching to https. I tray setup a redirect:

But it does not work. There is no redirect. Any ideas?
