Continuous loading, windows Web server, IIS8

Hi
I have a wordpress on Windows 2012 R2 webserver, IIS8, and installed plugin vrm360.
The loader is just spinning.
This is the code
[vrm360 canvas_name=s1 model_url=https://www.maksim.si/wp-content/uploads/2020/09/s01_n.obj aspect_ratio=1.33333 hide_cmds=zoom]

I’ve put the same site on local development linux server, and works fine.
The code
[vrm360 canvas_name=s1 model_url=https://dev.maksim.local/wps2000/wp-content/uploads/2020/08/s01_n.obj aspect_ratio=1.33333 hide_cmds=zoom]

On both sites there is also .mtl file.

Any idea what on windows server is not working?

PS: The windows server was not my choise ??
