Hi Jingrui,

I believe it is not related to device type but the security control of browsers on different devices (esp. Chrome).

Tried “” and it runs fine on Safari but failed to load on Chrome and Edge.

  • Error in Chrome Browser Console like
  • Error with Permissions-Policy header: Unrecognized feature: 'interest-cohort'.
    Mixed Content: The page at '' was loaded over HTTPS, but requested an insecure element ''. This request was automatically upgraded to HTTPS, For more information see
    GET 403
  • Message in Safari Browser Console like
  • The page at was allowed to display insecure content from


Then tried “” and it runs fine on all browsers and devices I have (Mac, iPad, iPhone and Win Laptop).

Please have a try to storage the mp4 file on a server with “https”

Thanks and regards,
