981ed73 fixes the Symbol’s value as variable is void: straight-process-buffer error, but the Could not create connection to raw.githubusercontent.com:443 error indicates a networking issue, not a Doom issue. I suggest you try again.

If you work or live somewhere where githubusercontent.com is blocked, you may need to use a proxy, or install Doom from elsewhere.

Alternatively, you can install straight manually, like so:

# If your ISP or proxy doesn't allow you to install from
# raw.githubusercontent.com, then you'll have to install straight (our package
# manager) manually:
mkdir -p ~/.emacs.d/.local/straight/repos
git clone -b develop https://github.com/raxod502/straight.el ~/.emacs.d/.local/straight/repos/straight.el
