IP restricted videos

[budg3]

Found a type of video cipher that deciphers faultily: https://invidio.us/watch?v=sPFb_7jrDVo
It doesn't work with CloudTube either, but I can manage to download it with a dedicated downloading program (JDownloader 2).

Edit: Seems to be an IP restricted video. Doesn't work with European IPs, works with American IPs.

Appears to be working now, it may have just been that the signature changed and the site took a second to update.

[budg3]

Still doesn't work for me:

[omarroth]

Very strange, I'm assuming you're getting 403 on /videoplayback? Could you provide one of the sources that Invidious is providing?

[omarroth]

Both those sources work for me. When accessing them directly what error do you get?

[budg3]

403 Forbidden. Possible IP restricted video?
I tried with one Netherlands proxy and one German proxy and both failed, worked with an American proxy however.

[omarroth]

Using the site above, I can verify that it returns 403 using Netherlands and I can verify that it returns 403 using German proxy. Using a proxy from here though, it appears to work. The issue then may be with YouTube blocking specific proxies, and not the user's IP address.

Another evidence for this is that YouTube lists "DE" and "NL" as allowedRegions (you can see that here), so it would seem strange that it wouldn't allow German IPs to access video content.

[budg3]

My unmasked IPs' actual country code is listed in allowedRegions so it's strange alright. User/channel related or a faulty config at google?

[omarroth]

It's doubly-strange, because YouTube will happily provide /get_video_info to a German/Netherland proxy, but then immediately turn around and give 403 when that proxy attempts to request /videoplayback. The user/channel appears to be fine, so I would assume it's Google attempting to block popular proxies, although I'm having trouble finding a German proxy that even works so I can confirm this.

[narcolepticinsomniac]

I thought we were circumventing geo-blocking, but I ran into one in the U.S. too:

https://invidio.us/watch?v=xpWu4_hp00M

[omarroth]

Not currently. I would recommend opening a new issue on geo-restrictions, and we can have a discussion there on how they should be circumvented.

To clarify the distinction: for geo-restricted videos YouTube will not provide download video information to IPs in restricted zones. This issue however is very strange, YouTube will provide valid video information, but give 403s on attempting to access it.

[omarroth]

I recently found the maker of a userscript has encountered the same issue, with google randomly blocking IP ranges, which seems to indicate a faulty config, like @budg3 said. If so then this issue will probably be closed with #92.

another example: https://invidio.us/watch?v=Vs2StGdkGGI
works fine through youtube from belgium, works fine on invidious using VPN or proxy in US
doesn't work when accessing from invidious from belgium
maybe the googlevideo.com URL is different depending on the region? as a measure to block people from bypassing the youtube website/player when accessing videos?
that would be a plausible explanation, as that would cause invidious to fetch the URL from the country where the invidious server is hosted, which can't be accessed by people watching the video from some other regions

then again why would this only happen on some videos, and not all of them? 🤔

[omarroth]

Closing in favor of #92, since this is caused by a less-restrictive form of geo-blocking, and will be fixed the same way as #92.
