Description

Youtube-dl Canvas extractor for VRTnu fails to download json (warning) and eventually the file fails as well. From what I've looked at using git blame none of the code seemed to be altered recently, I guess something has changed on the content provider site, that needs to be matched in the Python code, regarding the title of the content. The issue is present for all the URL's I've tried on VRTnu. An account (https://www.vrt.be/vrtnu/#popover:profile) is needed to access this content

I did some further debugging, issue is with the extractor in combination with a .netrc file. User and pass on the command line just works fine. Closing this issue.
