Ok. Anyway, for some reason, all your non-browser cURL requests are triggering Firewall challenges at Cloudflare.
This is a bit strange, because this behavior is not normal, and I can't just disable Cloudflare. I created a couple of RULES that should bypass the firewall when requesting the ZIP files, but it seems they are not triggering. Either it takes a little while, or there is something else, in which case I need to ask some questions in the Cloudflare community.
Please check a bit later (at least 4 hours from now) and then let's see. If still challenge, then I will need to post some questions to Cloudflare community. It's of course a bit strange that your cURL causes the Cloudflare challenge, as this is not normal.
