Google font not working on PC en smartphone

Hi,
On the website https://www.crkl.eu/ I use “Karmina” as main font. This is a google-font.
In my childtheme (CRKL) i wrote this code

add_filter( 'avf_google_heading_font',  'avia_add_heading_font');
function avia_add_heading_font($fonts)
{
$fonts['Karmina'] = 'Karmina';
return $fonts;
}

add_filter( 'avf_google_content_font',  'avia_add_content_font');
function avia_add_content_font($fonts)
{
$fonts['Karmina'] = 'Karmina';
return $fonts;
}

On my mac, the font is displayed as it should.
But on smartphone, tablets and pc, the font is replaced by another font.
What could be the problem?
