Problem loading fonts when uploading site to server

I'm using some fonts that I've stored inside a folder on my system. When I run the system locally there is no problem, however when I upload the server to the server (amazon) the fonts stop being displayed. Does anyone know what can it be? This is the code I'm using to load fonts into css:

The first font is normally displayed on the server, the other two are locally only

@font-face {

   font-family: 'tipografia';
   src:url("../fonts/MyriadPro-Regular.ttf");
}

@font-face {
  font-family: 'ocr';
  src: url("../fonts/ocra.ttf");
}

@font-face {
 font-family: 'bemio';
   src: url("../fonts/bemio.otf");
 }
