DESCRIPTION

youtube-dl crash randomly with a 403 Unauthorized wile crawling into udemy course. I have been able to download successly 35/150 videos about my course, but after a "first run", youtube-dl crash around 30, and on the second run, i cant even access to the homepage.

It look like udemy has implemented a system to detect the usage of this script, maybe a pause between 2 downloads could help to bypass this system;

I am getting the same Traceback.

If this can help for udemy-dl I am getting :

Traceback (most recent call last): File "/usr/local/bin/udemy-dl", line 7, in main() File "/usr/local/lib/python2.7/dist-packages/udemy_dl/udemy_dl.py", line 837, in main udemy_dl(username, password, link, lecture_start, lecture_end, save_links, safe_file_names, just_list, output_dest) File "/usr/local/lib/python2.7/dist-packages/udemy_dl/udemy_dl.py", line 658, in udemy_dl login(username, password) File "/usr/local/lib/python2.7/dist-packages/udemy_dl/udemy_dl.py", line 109, in login csrf_token = get_csrf_token() File "/usr/local/lib/python2.7/dist-packages/udemy_dl/udemy_dl.py", line 102, in get_csrf_token return match.group(1) AttributeError: 'NoneType' object has no attribute 'group'

So looking at it seems authorization issue. For the case of udemy-dl is about the csrf_token
