Can't download a stream recording, shows 403 error code.

[Vrata School]

Hello. Could you please help me? I can't download a particular video. I have the newest extension version 7.5.0.0. VDHelper shows the red icon and shows those errors .
Tried downloading via .ts chunks, but after combining them with Total Commander as decribed in various guides, the file is unreadable. The video in question: https://www.yoga.ru/ipractika/media/6368725/

There is a master manifest with this video showing 3 possible streams at various resolutions.  VDH does offer these 3 streams in its menu.  These variants show the relevant resolution in each respective entry in the VDH menu.  VDH also offers a 4th stream that does not show a resolution.  I believe (totally guessing here) this comes from a second manifest that appears when you launch playback of the video.  This second manifest appears to be the list of chunks making up that stream.  I didn't compare the URL of this second manifest to any of the entries in the master manifest but I'm going to guess it matches one of them.  I'm also going to guess this second manifest is for whatever happens to get chosen as the default resolution in the player.  This player has a little gear icon that allows you to select a different resolution.  I did not attempt to download any of these streams because the video is an hour and a half long.  I am not going to download something like that as a test on my slow connection.

A 403 error means you don't have permissions set that allow the web site to display the data you're requesting.  This is exceedingly strange since this web site is not password protected.  The site didn't prompt me to log in, which is a good thing because I don't speak Russian & it's unlikely I would have understood that's what it was doing anyway.  I was able to view the page & start the video even though I'm not in Russia.  However, I have encountered cases in which a download I had started, on a site that did not require an ID/password, progressed for a significant time & suddenly the web site decided to throw a 403 at me.  I don't know how such a decision gets made.  You'd think if you weren't permitted to do something on the site, it would tell you as soon as you launched your download, not after happily downloading for 10 minutes.  But I'm not an expert in these things.  If I had a nice, fast connection, I'd have tried to download all 4 streams using VDH.  If I had encountered any errors, I'd have tried them all with ffmpeg.  But you'll have to see if somebody else can try it.  On the surface, this looks to me like it really ought to work.  A 403 error does not seem to me like something VDH is doing.  VDH would be the victim in this case.  But I can't test this so let's hope somebody else can & does.
