    throw new Exception("Can not find ".$parts ['basename']." on server");
}
if ( $parts['extension'] == 'docx' ){
    header('Content-type: application/vnd.openxmlformats- officedocument.wordprocessingml.document');
    header('Content-Disposition: attachment; filename="'.$parts['basename'].'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    ob_clean();
    flush();
    readfile($docFile);
}else{
   header('Content-type: application/msword');
   header('Content-Disposition: attachment; filename="'.$parts['basename'].'"');
   readfile($docFile);
}

The solution for me was to add

 $fsize = filesize($docFile);
 header("Content-Length: ".$fsize);
