Html webapp doesn't run on chrome on iPad

Hi.
I’m creating a web app for an event and It would be awesome to use it on a tablet.or smartphone, instead of a computer.
On PC’s web browser it works heavenly. On an android smartphone it works, but finger movement doesn’t work (I can still use the app bottons) so I can’t orbit the mesh.

On iPad it finish downloading the data, but It can’t finish compiling and it return a generic error.
The page returns these warnings

this is a screen of the app

Any suggestion on how to make it work or documentation to study?
Thanks you in advance!
