font.css file only one font

/* === Lobster - regular */
@font-face {
    font-family: 'Lobster';
    font-style: normal;
    font-weight: 400;
    src: url("./fonts/Lobster-Regular.eot");
    src: local("Lobster"),
        local("Lobster-Regular"),
        url("./fonts/Lobster-Regular.eot") format("embedded-opentype"),
        url("./fonts/Lobster-Regular.woff2") format("woff2"),
        url("./fonts/Lobster-Regular.woff") format("woff"),
        url("./fonts/Lobster-Regular.ttf") format("truetype"),
        url("./fonts/Lobster-Regular.svg") format("svg");
}

Sorry, resolved

Wrong format

variants: ['200,300,400,500,600'],

Should be

variants: ['300', '400', '500', '700'],
