icons with fontawesome do not load css styles in android browsers

I have these icons that look good on PC but Android does not take styles. also an image in parallax does not appear and the menu does not appear, I'm using modernizr and I do not know if the error is here or in js ....

the console tells me this.

This site seems to use a positioning effect linked to the displacement. This may not work well with asynchronous panning;

Accessing with my public ip gives me this error.
