Why my Child Proxy Won't Connect HTTPS?

hi all

im stuck with this case where my child proxy won't connect to https

my child proxy (box1) connected with parent (box2)

in this condition, on the box2, there is no firewall.

when box1 request http://www.google.com and searching, there is no problem.. but when every request https such gmail.com, there is a notification error from server like this:
