Font-face not working in ubuntu for a site done with wordpress

Here is the thing I just uploaded to a remote server a site developed in wordpress with a custom web font using Font-face and it works fine in OS Windows and Mac the issue is when viewing the site in an Ubuntu, and I assume, others Linux enviroments.

This is the font-face chunk of code I use in the style.css

@font-face {
    font-family: 'vijayaregular';
    src: url('./estilos/vijaya-webfont.eot');
    src: url('./estilos/vijaya-webfont.eot?#iefix') format('embedded-opentype'),
         url('./estilos/vijaya-webfont.woff2') format('woff2'),
         url('./estilos/vijaya-webfont.woff') format('woff'),
         url('./estilos/vijaya-webfont.ttf') format('truetype'),
         url('./estilos/vijaya-webfont.svg#vijayaregular') format('svg');
    font-weight: normal;
    font-style: normal;
}

And this is how I call the font type:

body{
    background:#ffedbc;
    font-size:12pt;
    font-family: "vijaya", "open sans", Arial, Helvetica, sans-serif;
    color:#970d34;
}

This issue only happens in Ubuntu, as I said before, the code doesn’t seems to be loading any of the fonts but Sans-serif.

I leave the site so you can have a look, please nevermind the two stylesheets and two jQuery links that was just me trying crazy stuff.

Any responses will be welcome!

Thanks before hand!
