pfSense

I just upgraded from 2.4.1 to 2.4.2 but after the upgrade IPv6 is not working anymore. After checking the logs I see that the DHCPv6 client fails to start with these errors:

Nov 21 21:01:57 dhcp6c 60323 failed to open /usr/local/etc/dhcp6cctlkey: No such file or directory
Nov 21 21:01:57 dhcp6c 60323 failed initialize control message authentication
Nov 21 21:01:57 dhcp6c 60323 skip opening control port
Nov 21 21:01:57 dhcp6c 60323 /var/etc/dhcp6c_wan.conf:2 IA_PD (0) is not defined
Nov 21 21:01:57 dhcp6c 60323 failed to parse configuration file

So I enabled debug and now I get these log entries:
