Why doesn't IE 11 accept font-family: 'Proxima Nova ExtraCond ExtraBold'?

Question

css

Connected two fonts via @font-face

@font-face {
    font-family: 'Proxima Nova Extra Condensed Extra Bold';
    src: url('../fonts/ProximaNovaExCn-Extrabld.eot');
    src: local('☺'),
         url('../fonts/ProximaNovaExCn-Extrabld.eot?#iefix') format('eot'),
         url('../fonts/ProximaNovaExCn-Extrabld.woff') format('woff'),
         url('../fonts/ProximaNovaExCn-Extrabld.ttf') format('truetype');
    font-weight: normal;
    font-style: normal;
}
@font-face {
    font-family: 'Solomon Sans Black';
    src: url('../fonts/Solomon Sans.ttf');
    src: local('☺'),
         url('../fonts/Solomon Sans.ttf') format('truetype');
    font-weight: normal;
    font-style: normal;
}

The first one is somehow not accepted by IE 11, there are no problems with the second one, I tried to change the sequence of connecting formats, added and removed (?#iefix), I connected format ('eot') to ('embedded-opentype') using myfonts script.
I thought it was a broken eot file, I converted woff to eot.

Of course, I apologize, I answer the question with a question, but why do you actually need eot? woff has been perfectly supported since ie 9. I forgot when I included anything other than woff and woff2 from fonts.
Delete it to hell and leave woff, maybe this is how you solve your problem,
