Operating System (name/version): Windows 10 Pro 64-bit Python version: 3.8 youtube-dl version: 2020.09.20 edx-dl version: 0.1.13

When I try to retrieve course videos using: edx-dl -u name@xxx.xx https://courses.edx.org/courses/course-v1:MITx+7.05x+3T2020/course/

the following error appears: edx_dl version 0.1.13 Password: Building initial headers for future requests. Getting initial CSRF token. Found CSRF token.

I am getting the same

The solution provided in https://github.com/coursera-dl/edx-dl/issues/631#issuecomment-667852988 worked for me as well:

I'm not an author of the tool, but you can fix it by changing line 425 of edx_dl.py which specifies the User-Agent attribute of the http request header. Change 'User-Agent': 'edX-downloader/0.01', to 'User-Agent': 'Mozilla/5.0', and it will work.

Did you change something else too? I and a few other people are getting empty folders when we do this.

My apologies, I thought this is a solution, but it only worked for one course (no idea why), the others just produce empty folders.

Ah okay. This is weird. I think this stopped working after edX changed the UI. Thanks though !
