Some video embeds are not working

Hello everyone,

I have an issue with embedding Vimeo videos on my WordPress website. I suspect it might be a hosting-related issue similar to the one discussed in this thread. To isolate the issue, I have created a separate WordPress site on my hosting and a post with a Vimeo embedding. The link to the page is the following:
https://test.amirkhanov.net/2020/11/03/test/

It tried to disable IPv6 support on my WordPress site by adding the following code to functions.php

add_action( 'http_api_curl', function( $curl_handle ) {
   curl_setopt( $curl_handle, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
});

Unfortunately, this did not change the situation.

Also, I have uploaded the following code to test if my sever is blocked by YouTube or Vimeo:

<?php

// Download this file to your WordPress install and name it test.php
// and then access it via test.php?type=vimeo

if ($_GET['type']=='vimeo') {
  $url = "https://vimeo.com/api/oembed.json?url=https%3A//vimeo.com/76979871";
} elseif ($_GET['type']=='youtube') {
  $url = 'http://www.youtube.com/oembed?url=http%3A//youtube.com/watch%3Fv%3DM3r2XDceM6A&format=json';
} else {
  die('Must specify type: vimeo/youtube');
}

echo "<pre>";
echo "Source IP: " . file_get_contents('https://api.ipify.org') . " (where the script is being called from)\n";
print_r(get_headers($url));

?>

However, it looks that my server is not blocked.
https://test.amirkhanov.net/test.php?type=vimeo
https://test.amirkhanov.net/test.php?type=youtube

Do you know what might be the problem? I also can provide admin credentials to the website if you need them (this is a purely testing website).
