Steps to reproduce

Hi,

When I try to download a YouTube video, the video information is detected correctly and the thumbnail is downloaded successfully, but the actual video download fails with a 403 Forbidden error.

The log shows:

[info] 8yE6G1Lup1s: Downloading 1 format(s): 398+140
[info] Downloading video thumbnail 41 ...
[info] Writing video thumbnail ...
[dashsegments] Total fragments: 25
[download] Got error: HTTP Error 403: Forbidden.

The thumbnail is downloaded, but the video itself is not, and the task eventually fails.

Could you please check if this is a known issue or if something needs to be updated?

Thanks!
