Google Font doesn't load in Safari! Options

[Bigg Bigger]

Hello guys,

Im working on this website:
poschbuchhandlung.at/hu/index.html
I tried to implement a Google Font with @font-face:

@font-face {
font-family: 'Inconsolata';
font-style: normal;
font-weight: 400;
src: url('../fonts/inconsolata-v18-latin-regular.eot'); /* IE9 Compat Modes */
src: local('Inconsolata Regular'), local('Inconsolata-Regular'),
url('../fonts/inconsolata-v18-latin-regular.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
url('../fonts/inconsolata-v18-latin-regular.woff2') format('woff2'), /* Super Modern Browsers */
url('../fonts/inconsolata-v18-latin-regular.woff') format('woff'), /* Modern Browsers */
url('../fonts/inconsolata-v18-latin-regular.ttf') format('truetype'), /* Safari, Android, iOS */
url('../fonts/inconsolata-v18-latin-regular.svg#Inconsolata') format('svg'); /* Legacy iOS */
}

This does work in Firefox but not in Safari!And I can't figure out how, I already spend furious hours browsing the internet!
What is the problem? Do you have any guess?
Thank you very much
