Video streaming don't work on Framework7

Hi everyone, I can’t understand what I’m doing wrong, I tried to include the Cloudflare streaming service in a simple page made with Framework7 V4 and the video doesn’t seem to be able to load the data for some kind of restriction, thinking it was a problem domain, I tried to build a simple HTML page and including the video, it works perfectly.

I use this code:

              <stream src = "5d5bc37ffcf54c9b82e996823bffbb81" controls preload height = "240px" width = "480px"> </stream>
<script data-cfasync = "false" defer type = "text / javascript" src = "https://embed.cloudflarestream.com/embed/r4xu.fla9.latest.js?video=5d5bc37ffcf54c9b82e996823bffbb81"> </script>

the page that works is on https://f7.lhsgroup.it/test.html (without Framework7), while the one that doesn’t work (with Framework7) is https://f7.lhsgroup.it/.

Can anyone help me make cloudflare videos work?
