Error: Type=AAAA Host Not Found — Troubleshooting Guide

The error "Type=AAAA Host Not Found" occurs when a DNS query for an IPv6 address (AAAA record) fails. This typically happens when the domain does not have an AAAA (IPv6) record, or the DNS server is misconfigured.

Add an AAAA Record to Your DNS

If your domain lacks an AAAA record, follow these steps:

1. Log in to your DNS provider?s control panel (e.g., Cloudflare, cPanel, ISPmanager).
2. Navigate to DNS Settings or Zone Editor.
3. Click Add Record and select AAAA (IPv6 Address).
4. Enter:
   • Host: @ (or yourdomain.com)
   • IPv6 Address: Your server?s IPv6 (e.g., 2001:db8::1).
5. Save changes and wait for DNS propagation (up to 24 hours).

Verify IPv6 Support on Your Server

1. Check if the server has an IPv6 address assigned:

   ip -6 addr show

2. If IPv6 is missing, request an IPv6 from your hosting provider.

Use an A Record Instead of AAAA (If IPv6 Is Not Needed)

If your server only has an IPv4 address, remove the AAAA query and use an A record instead:

1. Delete the AAAA record from DNS settings.
2. Ensure an A record (IPv4) exists:
   yourdomain.com > 192.168.1.1
3. Flush DNS cache:
   Windows:

   ipconfig /flushdns

   Linux/macOS:

   sudo systemctl restart nscd

Conclusion

The "Type=AAAA Host Not Found" error is a DNS-related issue indicating a missing IPv6 record. By checking for an existing AAAA record, adding one if necessary, or falling back to an IPv4 A record, you can resolve this error and ensure proper domain resolution.
