I'm seeing the same error, same version (installed directly from repo), Verbose logs: |
|
Wait NOW it is working again, i just tested YOUR youtube link and it works now with mine too... |
Do you have the verbose log from when it worked? Do you know if it was using the same player id A couple of videos I am trying to pull are not pulling at the moment with this error and using the same player Id as your verbose log for the failure, |
|
No I dont have it but I can MAKE ONE! redownloads video |
Yeah, it looks like it changed to a different player ID when it worked. Player Id when error: 590f65a6 |
|
We can acquire the problem player JS and find out what feature breaks the n-sig descrambling. If this is a roll-out to |

I'm getting same error, how to fix it elegantly |
|
Is there a way to get a specific player in ytdl? That would probably be helpful. Also I got the bad player RNG again... |
|
maybe the trouble is related to https://techcrunch.com/2024/06/16/youtube-is-testing-another-way-to-combat-ad-blockers/ |
|
Ironically, a page that doesn't display without a pointless interstitial page. It's not clear how what TC describes would be having this effect. There are two issues:
At yt-dlp, people have observed getting 403 with Web formats when using browser cookies, but not generally without cookies, unless YT bans your data centre, VPN, or bulk downloading IP address. |
|
Need me to do something? I got the Issue again, with the same Player, so I might be able to reproduce it again if need be, unless youtube randomly decides to give me a working player again. |
|
The descrambling problem is a parsing error that will be patched soon. As to "getting 403 with Web formats when using browser cookies", I can't see any reason why that should succeed when it fails with yt-dlp. Review the linked yt-dlp issue (and its related issues) for guidance. Maybe we'll be able pull the experimental OAuth2 implementation from https://github.com/coletdjnz/yt-dlp-youtube-oauth2. |

Wait you said web formats? does the mp4 format at ID 18 count as that? Also I did wipe the cookies File in my case, it was a File I needed a few months/years ago to get youtubedl to work at all. |
|
yt-dl only extracts Web formats, except for age-gate bypassing. So we can't (without changing the extractor code) use the work-around of fetching the formats as if we were an iThing that yt-dlp users have (since the yt-dlp extractor can get any or all of the various format groups that the YT webpage and APIs offer). |
|
I have the same problem, using new, nightly build of youtube-dl 2024.06.12 (latest). Anything can be done to help? |
@astralblue: Which version it patches? Also, due to inability to figure out exactly which version it applies, I tried nightly build without the change and it succeeded after 30+ tries. |
|
Curiously, yt-dlp does not have this issue. I thought the jsinterp in yt-dlp and youtube-dl were pretty much on par? |
3 tasks
|
Yes, but there is a bug in the evaluation of But more significantly, the links from the web player are getting 403 regardless of cookies, unlike in yt-dlp/yt-dlp#10046. |
|
Ah okay makes sense, so it seems like incorrect/missing nsig is no longer punished by throttling, but by 403. |

I've been getting similar results for a while. I don't see player 5604538d mentioned in any issues. I've tried with an empty cookie file and with cookies exported from a working firefox session (log using latest daily build attached). Edit: also pasted log inline as it only appeared as a downloadable attachment. |
|
Please use the nightly build here. The ytdl-patched repo is not updating from here, actually hasn't been doing so for some time. With today's update (not yet committed): |
|
Thanks very much. I hadn't appreciated that '-U' wasn't upgrading to latest. |
|
As I guess, I have the same problem with v2024.08.02, with one video in particular. It happened with others but one or two restarts were sufficient to overcome it. Not this time though. |

Verbose log
and from the youtube-dl-nightly the same type of error
Description
using both youtube-dl and youtube-dl-nightly as compiled from their respective github master repos!
Error 403 when downloading from youtube, resetting cookies and grabbing new cookies did not solve it this time. It worked like 3 hours or so ago, though i DID have issues two days ago where I could fix it myself with the cookie reset. Them Googel Devs trying to mess with downloaders and ad blockers again, I'm guessing.
Extra Info, VPN in Canada does not help, so I am certain this is not only a Germany Issue.
