DHCPv6 server not giving out addresses to hosts

Hi,

I tried to configure a DHCPv6 server on a Mikrotik hAPac² running 6.48.1 OS.
The result is that the clients cannot get IPv6 address from the server.
Tried more configuration possibilities, such as https://wiki.mikrotik.com/wiki/Setting_up_DHCPv6 but still, nothing better.

Could someone give me more information about this behavior please? Is it a bug or…?

Thanks is advance.
Best Regards

As stated in https://wiki.mikrotik.com/wiki/Manual:IPv6/DHCP_Server “RouterOS DHCPv6 server can only delegate IPv6 prefixes, not addresses.”
