It's a matter of JS and site blocking HTTrack.

httrack <https://drawabox.com/> -O drawabox \
  --cookies-file cookies.txt \
  -F "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML,
like Gecko) Chrome/128.0.0.0 Safari/537.36" \
  -r2

With cookies.txt captured inside the navigator. This is a bit cumbersome, but
the site has JS gating, which is really difficult to bypass.

Building cookies.txt
--------------------

The easiest way is a browser extension. Search your browser's add-on store for
"cookies.txt", and several will export the Netscape format HTTrack
reads. Export it from a tab where drawabox.com is loading normally, then save
the file as cookies.txt in your project directory, next to
hts-log.txt.

You can also write it by hand, because you only need two lines. Press F12 in
your browser, open the Application or Storage tab, and select
Cookies. Find boxses and timezone, and copy the value of each. Then put this
in cookies.txt:

drawabox.com  FALSE   /       TRUE    1789735536      boxses 
PASTE_THE_BOXSES_VALUE
drawabox.com  FALSE   /       TRUE    1789217136      timezone       
PASTE_THE_TIMEZONE_VALUE

The seven fields on each line are separated by TAB characters and not by
spaces. A file written with spaces looks right and does nothing, so check
that first if the waiting page comes back. The long number is the expiry date,
and any date in the future will do.
