Forward URL does not go to https

I’ve setup the below Forwarding URL
** Forwarding URL (Status Code: 301 - Permanent Redirect, Url:
Problem is that when I type it redirects to

$ curl -vso /dev/null 2>&1 | grep -e Moved -e Location < HTTP/1.1 301 Moved Permanently < Location:
It is supposed to redirect to httpS://
Does anyone know why it fails to properly redirect to HTTPS?
