Same here. Everything worked fine last month, but I keep getting
Error opening input files: Server returned 401 Unauthorized (authorization failed)today no matter whichvideomanifestlink I chose. Some additional authentications are likely being implemented on the server side. Hopefully someone could find a new way to get ourselves in.Update
After some digging, the error message seems to be due to a missing access token in the URL, the query parameter
access_tokenhas to be present in the URL, which is usually missing now when we use the traditional way to retrieve, resulting inError opening input files: Server returned 401 Unauthorized (authorization failed).Workaround (What is currently work for me)
