IPv6 on the LAN - DHCPv6 Not working / Default gateway not pinging on IPv6 Only

I have created a DHCP IPv6 Server, but nothing is working. (Nothing getting an IPv6 automatically / nothing talking to its DG)

Above is a VM on vcenter not pulling anything with DHCPv6

Sophos is a VM. And the above Ubuntu server screenshot is a VM with an attached VLAN 40 interface

The VM comes in through this interface:

and I have this DHCP server configured:

But nothing in VLAN 40 is pulling an IP.

Any idea what I am doing wrong?
