TikTok embed return 403 on some computers

Question

I am trying to create a web app that displays TikTok videos in it. In most computers, that works fine, but for one of the clients, the video is loaded but can not be played. I get the following errors in the console: (sorry about the bad image it is the best I got)

Notice that the URL returned 403 is v16-web.tiktok.com while I send the get request to tiktok.com.

This is the relevant code:

function embed_post(link) {
    fetch("https://www.tiktok.com/oembed?url=" + link)
        .then(response => response.json())
        .then(data => {
            $("#post_view").html(data["html"])
        })
}

Where "link" is the link to the video in tiktok that looks like www.tiktok.com/{user secUid}/{video id}

Does anyone know how can I fix it? Thanks for the help.

403 means the server side judged the authority of the media requesting and failed. Cause the TikTok video load in a iframe, a possible reason is that the browser in those clients forbidden carrying cookies when requesting the media in a iframe (like in a Incognito mode).
