USDZ file not loading on Apple Vision Pro

I'm working on a school project that allows users to open a .USDZ file (using Quick Look) on the webpage while using Apple Vision Pro to put the object in their physical envirnment, the project is deployed on Vercel. I'm testing the page with my apple vision pro, when I click open the .USDZ file, I'm seeing a triangle with an exclamation mark while it's trying to load, but it won't load. Does anybody know how to troubleshoot this issue?

Please provide a link to the USDZ if you can, or use Feedback Assistant (https://feedbackassistant.apple.com/) to file an issue and provide more details.

You may also want to validate your USDZ file.

See Validating feature support for USD files.

I downloaded the sneaker Airforce USDZ file from Apple Quick Look for testing, my code looks like this:

<a rel="ar" href="images/sneaker_airforce.usdz">Click to view in AR
            <img src="/images/thumbnail.png" alt="View 3D Model">
</a>

if you are using a file that you know should work, it might be the web server not serving up usdz files correctly (with the right mime-type)? is it possible to share the URL to the webpage?
