wayback machine does not archive linked content ( documents, files ) unless the link is explicitly archived. E.g if your page has two links to PDF files and one video. Unless you open the archived page and click on that link to archive it using the web.archive.org/web/ url it
will may not be archived. Images get archived automatically, but in the case of this page the link to load the flash player got archived , ( in fact it remotely loads the latest version of the flash player , right click on the player area and it will show the version number "
About Ruffle (nightly 2024-01-08)" , but video content which is loaded separately never got archived , that never got archived.
Check out your link on archive.is ... same issue
your video is available on xvideos, not sure if this is the correct length though
