Download fails after completing Course Overview download from plurals*ght course

[ajitarya]

Hi Guys,

My friend keeps on getting the 403 everytime after downloading the 1st Course Overview video. He is using "Export Cookies" firefox v57 add-on to download the pluralsght cookies file. It formats it into the Netscape type format which he is plugging in with youtube-dl.exe (located in "C:\Pluralsight DLs" folder)
He have the Monthly plus subscription of pluralsght.

He also tried to download the playlist at json id sequence number 10 but that failed as well. Please help.

C:\WINDOWS\system32>youtube-dl.exe --cookies C:\Users\DUMMY\Desktop\cookies.txt -o "C:\Pluralsight DLs\%(playlist_index)s - %(title)s.%(ext)s" --min-sleep-interval 35 --max-sleep-interval 37 https://app.pluralsight.com/library/courses/developing-dotnet-microsoft-azure-getting-started/ --playlist-start 10 --verbose
