Thank you for reporting this issue.

It is not an issue with Emacs itself, but rather with the alpha.gnu.org
server access over HTTPS.

It appears that

  https://alpha.gnu.org/gnu/emacs/

does not point to the pretest directory of Emacs, but rather to

  https://ftp.gnu.org/gnu/emacs/

I'm not sure who I should forward this email to, but I'm putting
<webmaster@gnu.org> in the Cc.

Cheers,
Nico
