Troubleshooting DHCPv6 when it won't start

[kryptonian]

It seems that for whatever reason, DHCPv6 dislikes my DNS address despite it working previously?

The DNS address in question is an ULA,fdbc:baa4:65a9::4

Is there a place where that conf file would be persisteted so I can look at it? I cannot find the file in /etc/dhcpdv6.conf?

Running OPNsense 24.7.3_1

Use RADVD to tell your IPv6 neighbours what DNS to use.

Well, first check around line 20 of /var/dhcpd/etc/dhcpdv6.conf -- allegedly it only desires a semicolon.
