<p>Hello,<o:p></o:p></p>
<p>thank you for using Kea :)<o:p></o:p></p>
<p>This is problem of communication between kea-ctrl-agent and kea-dhcp6, two most common issues in this case are:<o:p></o:p></p>
<p> - kea-dhcp6 is not running / failed to open socket<o:p></o:p></p>
<p> - there is misconfiguration of sockets (configuration in kea-ctrl-agent has to point to the socket that kea-dhcp6 is opening)
<o:p></o:p></p>
<p>Regards<o:p></o:p></p>
