ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:2635)

[JackyWay]

Thank you so much for this project; it has greatly assisted me in self-studying and easily reviewing the course materials.

When I was downloading one of the courses, it initially ran smoothly. However, after downloading for a while, I encountered the following error and the download failed. I am using Windows 10 as my operating system.

Is there a way to fix this issue? Once again, thank you so much for this project.

Do I need to re-download the course, or can I resume from where it was interrupted?

Regarding the previous issue, I have tried downloading again, and it now works. However, it appears that there is no option to skip the downloaded file, resulting in a re-download for the entire course.

I am currently encountering another issue and will attempt again. It would be greatly beneficial if we could resume from where we left off or skip the already downloaded files. Thank you.
