Hello,
I'd like to report an issue that happens when I try to download a course.
I don;t know if this project is still maintained, hope it is as it's the best projects I've found on Internet.
When downloading a course it starts and goes well, fetches about 200megs of data and then fails, then the retry logic tries to download from where it's failed. Here's a piece of log of the app:

I seem to have this same error from MacOS CLI. Downloading all the videos, but failing to download the exercise files.
