IPv6 not working

[dcol]

I have no IPv6 connectivity. Had it before the last update, but not sure if that had anything to do with it.
Dashboard shows dhcpv6 and a WAN_DHCP6 gateway running
LAN has iPv6 Configuration Type as track interface with prefix ID 0
WAN has IPv6 Configuration Type set to DHCPv6 and Prefix delegation size=64
There are no VLANs
Unbound has DNS64 Support Disabled
Custom options are

server:
do-not-query-localhost: no

forward-zone:
   name: "."
   forward-addr: 127.0.0.1@5353
   forward-addr: ::1@5353

On the client side, IPv6 is enabled DHCP. ipconfig shows a Link-local IPv6 Address.
Any help appreciated to get IPv6 working again.

Good chance you are hitting the bug referenced.  Only fix is a reboot.
