Fonts not working with Axure Cloud

Hello!

I’ve been using a custom font for my prototype. I’ve tried used font mapping to make sure it shows up in the browser correctly. Basically in the font section I defined a font called Acier with the following font face:

font-family: 'Acier';
src: url("malaksadekapps.com/Acier-DisplayGris.otf");

And then mapped from the Acier on my laptop to that Acier. When I publish to Axure Cloud however, the setup doesn’t work. I have no idea what the problem could be!
