But if I try to use server file from same directory(server font file route) IE received this font I see it in dev tool but font not working and looks like standart font

Answer 1

I not found good solution, but I fixed it used base64 converter from this answer: Converting and rendering web fonts to base64 - keep original look

Converter:

function base64convert (files) {
  console.clear()
  const reader = new FileReader()
  reader.onload = (e) => {
    console.log(e.target.result)
  }
  reader.readAsDataURL(files[0])
}

<input type="file" onchange="base64convert(this.files)">

And included my ttf font file as base64 string.

@font-face {
    font-family: 'myfont';
    src: url("<<copied base64 string>>");
}
