I have a similar issue to that which is highlited at https://www.pythonanywhere.com/forums/topic/2688/
the only difference is that I am using flask, and the module I am using is pytube. I trust that you shall help, the error message displayed is:

Answer 1

Youtube doesn't allow downloading videos through their API, so all of the scripts that download youtube videos scrape the www site, and we don't allow scraping from free accounts.
