Lightsail revert back to ipv6 DNS not working

0

I disabled ipv6 in order to equip my LightSail instance with an ipv4 SSL certificate. The DNS resolution never worked after a few hours of waiting. nslookup never received an ipv4 address.

I re-enabled ipv6 DNS, which assigned a new ipv6 address to my instance. After another few hours, there are still no nslookup DNS resolution.

What else can I do besides perhaps recreate my routing in Route 53?

Hi, thank you for reaching out, when you re-enable ipv6 on Lightsail instance, you will be assign a new ipv6 address, you will have to update your Route 53 to point your domain to a new AAAA records for the new ipv6 address. After updating your Route53 settings, you will be able to see the ipv6 address from nslookup

    This is not correct. There is no need to create a Route 53 AAAA Record. Instead, there is only ONE way to fix this issue. It is:

    Go into the LightSail instance Network tab to ensure ipv6 is enabled. Then go into the Domains tab and add new entries for your TLD and *.<TLD>. Then wait for a bit for NIC propagation. When your nslookup now succeeds, you will notice there are NO Route53 records, not even a registered domains in Route 53 is showing your domain (so, must be magically working)
