Why can't fonts be connected?

Question

css

Goodnight!
I've never had any problems connecting fonts, but on this site font-face refuses to work.
The site is on a subdomain. CMS: Joomla 3.6.5. The template decided to take the standard one: protostar.
css file created a new one and connected to the site, all styles work fine.
I connect the font with the following code:

@font-face {
font-family: "UniNeue";
src: url("../fonts/UniNeue.eot");
src: url("../fonts/UniNeue.eot?#iefix")format("embedded-opentype"),
url("../fonts/UniNeue.woff") format("woff"),
url("../fonts/UniNeue.ttf") format("truetype"),
url("../fonts/UniNeue.woff2") format("woff2");
font-weight: normal;
font-style: normal;
}

The path to the file is 100% correct.
I have already read a lot of articles, I have not found anywhere what could be the reason ... Maybe because of the subdomain? Does anyone have any idea why the font is not loading?

Answer 1

Syntax? NOT?

@font-face {
font-family: "UniNeue";
src: url("../fonts/UniNeue.eot");
src: url("../fonts/UniNeue.eot?#iefix")format("embedded-opentype");
url("../fonts/UniNeue.woff") format("woff");
url("../fonts/UniNeue.ttf") format("truetype");
url("../fonts/UniNeue.woff2") format("woff2");
font-weight: normal;
font-style: normal;
}

Or the paths are crooked.
