This issue is a pretty poor job.. but I also had this problem. I guess its possible udemy has just started using Cloudflare. I was trying to download this course: https://www.udemy.com/course/dr-ks-complete-first-semester-general-chemistry-i-course/ I am on Windows 10 and live in Australia. I've no idea if the location is relevant but it's possible. I've never tried to download any other courses before, I was already logged in when I tried it, it might be worth testing it after making sure you are logged out of udemy... just trying to think why Cloudflare captcha would be triggering.

I 'm using a third party module/lib and handled the exception simply. the alternative way is to use cookie based auth instead of user/pass
