Custom fonts don't appear in the website

Hi there:)

I'm used to add some custom fonts but here ! two hours after, can't see why one of the two don't show up :(

I do add my fonts in the theme folder (fonts)
and add @font-face in style.css or customizer to see if it made a difference but nope :(

One works and not the other.

@font-face {
    font-family: 'toto';
	src: local('toto'),
	src: url('https://www.colormyweb.pro/Buxerolles/wp-content/themes/Buxerolles/fonts/toto.ttf');
}

If you see here, you may catch it (https://www.colormyweb.pro/Buxerolles/wp-content/themes/Buxerolles/fonts/toto.ttf)

Really tried everything (rewrite names, with or without dashes etc...) without any success, it's like they're s.think blocking it :(

Any idea where would it come from ?
Thx a lot !!
