Facvicon shows in Dashboard, not login

I used this statement in the functions file to get the favicon in the admin(dashboard) but it doesn’t show in the login (where you login).

function favicon4admin() {
echo ‘<link rel=”Shortcut Icon” type=”image/x-icon” href=”https://gardengoddesses.org/wp-content/themes/acoustic_v102/images/favicon.ico&#8221; />’;
}
add_action( ‘admin_head’, ‘favicon4admin’ );
