root@test:~$ dnslookup 'example.com' 'https://[2001:470:20::2]'
dnslookup v. 1.8.1-8619
2023/04/01 00:09:52 [fatal] Cannot make the DNS request: requesting https://[2001:470:20::2]:443: Get "https://[2001:470:20::2]:443?dns=AAABAAABAAAAAAAAB2V4YW1wbGUDY29tAAABAAE": x509: cannot validate certificate for 2001:470:20::2 because it doesn't contain any IP SANs
Checking the certificate in a browser also fails because of the certificate issue. Is this the right area to report this for the public recursor not working properly?
