@dstftw Duplicate of which please? Having this issue.

I never found the duplicate issue. I solved the issue by using cookie based authentication.

@harroguk Thank you. Such a frustrating that it's hard to find the 'master issue' in the pile of dulicates.
After searching for a while I think they're marked as duplicates of the 'Youtube: authentication failure' issue linked in the reply I made on 'Youtube : Can't download my "liked" playlist'
