I get now also the 403 Firbidden error when calling
var streamManifest = await youtube.Videos.Streams.GetManifestAsync(video.Id); on all the videos I try.
I use also version 6.5.0.
A few days ago it still worked.

hi there
been trying this now, and getting "forbidden" on any video...

Same here...

Is this happening for every1 or is just my IP blocked?
Because with a browser, I can watch videos when logged-in.
In Incognito mode however, videos not playing... is this a block sign?

Well, it was a temporary block. I tried again after a few days and everything worked just fine. Maybe my IP was renewed by the ISP.

Please take a look at the downloader variant I have coded:
https://www.youtube.com/watch?v=cuSokN7jVCk

Still not working for me tried with a vpn aswell still no luck

Same issue here on version 6.4.2 and 6.5.1:
System.Net.Http.HttpRequestException: 'Response status code does not indicate success: 403 (Forbidden).'
at last line of TryGetContentLengthAsync:

response.EnsureSuccessStatusCode();

Same issue with all videos I have tested. Location is Germany, if that matters. Same result on VPN. Using youtube in incognito mode works without problems. I can provide further information and help debugging if wanted.

Same here

Same issue for me :(

I can sometimes reproduce this locally but not consistently. Any help is appreciated.

From my experience, just spam video downloads or use a large playlist (around 1000 videos) and it will reproduce consistently. I think that its just youtube rate limiting and throwing a 403 error instead of the expected 429

Another observation: the “forbidden” issue now occurs consistently for all YouTube and YouTube Music URLs, but not seen for YouTube Shorts URLs. YTE v6.5.4

This can be reproduced from YoutubeDownloader

Same with v6.5.5 (2025-10-13) tested and worked fine, today(2025-10-14) it seems was update from youtube all videos on GetManifestAsync returns with 403, usually it helped jumping from 6.5.1-6.5.4 versions, but today it completely blocked

It's working for GetManifestAsync, if you remove this request in StreamClient.cs (l. 71) file :

using var response = await http.GetAsync( // Try to access the last byte of the stream MediaStream.GetSegmentUrl(url, contentLength.Value - 2, contentLength.Value - 1), HttpCompletionOption.ResponseHeadersRead, cancellationToken )

But the problem is still here on DownloadAsync...

Same here for about a week now. Until yesterday it helped, to get a new IP address by my ISP. Now this doesn’t work anymore. Every video fails with 403 forbidden. NewPipe 28.0 is not affected and still works. Thanks.

Same here

YouTube updated to a new version and changed their player, along with a lot of behavior related to fetching streams.

It works great here https://ytdown.io

As mentioned in this previous comment, there's an n parameter in the googlevideo.com links used to get stream chunks, and you'll get a 403 response if it's not present. One workaround I've found is, if you start playing a video in a web browser then copy the link it uses to get stream chunks, you can use that to send requests.

Should be fixed via #919. Tested locally.

@pictos

I attempted a similar fix, just didn't find the right client values myself. This seems to have taken care of it for me as well! Thanks @pictos & @Tyrrrz !
