Describe the bug
If the duration of the video is more than 10 minutes (for example CompTIA Cloud+ Cert Prep (CV0-003):1 Architecture, Design, and Security), the download lasts about a minute and then is interrupted. After the fifth attempt we receive a message: Course downloader Failed.

Operating System
Windows 10
