<div>For some reason they fail to connect. I have no firewall between/on the servers and they can ping each other. Trying to connect manually gives me the following error:</div>

<div> </div>
<div>Any idea what this "UnknownMandatoryTag" means?</div>

<div>Thanks in advance for any help or advise.</div>
