Dynamic DNS Client gives an error that it can't find IPv6 address when WAN interface is a LAGG
I'm trying to get the Dynamic DNS to update my ipv6 address with Amazon's Route 53 service. However, I'm seeing an error in the log that seems to suggest the Dynamic DNS client is struggling figure out the IP address of my WAN interface, maybe because it's a LAGG?
The interface does have a valid ipv6 address so far as I can tell (I use Comcast Cable). I've attached the relevant screenshots. Please let me know if you need any other logs.
I'm using the latest pfSense:
