Why is the font not working in IE?

Question

css

Hello! Added the Open Sans font. I downloaded the fonts from google font (more precisely, I took the css link that google gives and downloaded the fonts). It works great in other browsers, but not in IE.
I connect like this:

@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 400;
  font-display: swap;
  src: local('Open Sans Regular'), local('OpenSans-Regular'), url('/fonts/open-sans-c-r.woff2') 
  format('woff2');
  unicode-range: U+0400-045F, U+0490-0491, U+04B0-04B1, U+2116;
}
/*Здесь такой же код, но с другими font-weight и шрифтами*/
