What exactly am I missing?

Answer

Hello.

Is IPv6 available not only for Lightsail but also for the connection source?  
Also, check if Lightsail recognizes IPv6.

Answer

Hi,

Are you sure your local machine such as laptop has an IPv6 address, allows IPv6 traffic/DNS/etc and your Internet Service Provider (ISP) supports IPv6 ?

You could try some online tools to confirm your local IPv6 setup to ensure the issue isn't at your local machine side.

Thanks
