        If you have 3rd or even 4th level subdomains like <code>blog.example.com</code> or <code>en.blog.example.com</code> ,
        depending on your certificates coverage, you might need to setup them one by one (i.e. having two seperate certificate for <code>a.example.com</code> and <code>b.example.com</code>).<br>
        If you have a wildcard certificate that covers <code>*.example.com</code>, you can just enter <code>example.com</code> as server name in the form below to add a certificate.
