I'm trying to set up IPv6 Dynamic DNS on pfSense 2.8.1 via AWS Route 53 to track my WAN IPv6 address.

Whenever I use the Route 53 (v6) profile, it instantly fails. The dyndns system log shows:

/services_dyndns_edit.php: Curl error occurred: Could not resolve host: route53.amazonaws.com

• I know this matches Redmine #16249 / #16251 (forcing IPv6 on an IPv4-only AWS API endpoint), but that was supposed to be fixed in 2.8.1.
• If I run a standard curl -v https://route53.amazonaws.com/ from the pfSense shell, it resolves and connects instantly over IPv4.
• If I force IPv6 (curl -6), it fails because Amazon's endpoint doesn't have an AAAA record.

Things I've Tried:

• Forced default gateways explicitly (WAN_DHCP and WAN_DHCP6) instead of "Automatic".
• Cleared the DynDNS cache files completely via shell.
• Verified system DNS is bound to IPv4 (1.1.1.1).

Anyone else running Dynamic DNS on 2.8.1 successfully using the Route 53 (v6) profile? I feel like I'm taking crazy pills since this should be fixed already😅
