It seems they did blocking robots interring more than 20 videos.
At first I could only download 20 videos of 50. Then I got a 401 error.
And even from the site can not login.
It seems they recognized that my account is trying to connect too many times and not from the site login blocked it.
it's happened to you too?

If you can't login from the website there is nothing youtube-dl can do (since it uses the same method). For me it works as usual, just downloaded the whole course you provided two times without any issue.
