In most cases having a file version on CDN URL will likely generate an issue to load, below is the code to help you remove the file version of CDN URL:
function theme_name_cdn_version_remove( $src ) {
if( strpos( $src, 'cdn_name_here.com' ) )
$src = remove_query_var( 'ver', $src );
return $src;
}
add_filter( 'script_loader_src', 'theme_name_cdn_version_remove', 9999 );
