USDZ model isn't shown if the webpage has password from .htaccess

[GiovanniTurri]

Description

In my server I created .htpasswd and .htaccess files to protect an HTML page which have inside <model-viewer ios-src="mymodel.usdz">, but after the correct "login", in iOS devices (both iOS14 and iOS15) is triggered the error of not support of the model for that OS version (a typical error for unsupported features generated by big user's mistakes).
Removing only the .htaccess file, it works.

On Android, no problem in both cases.
I think there is something on the ios-src that can't handle a login or any type of barriers to access the resource.

Is there something I can do as a workaround (obviously, giving an external path to the usdz file stored in an other server works)?

Thank you so much

This looks to be a Safari/Quick Look bug, rather than anything we can fix in MV. Can you give a repro link? I can try to file a bug on Apple.

I see.
Yes you can reproduce at http://test.wear-mobile.com/ logging with user: git and psw: hub

@elalish do you think there can be a way to contact Apple to have more informations about this?
