SSL/TLS certificate

The site has been running for a while now, but I recently saw this message:
SniCertificate::CertificateInvalidError: Unable to verify challenge for vaughnheatingcooling.com: Invalid response from http://vaughnheatingcooling.com/.well-known/acme-challenge/gGan8etGBC6iGt1DQSWI5lUnYjiTRvGHyHPV4gWv9io [2604:a880:400:d0::6d9:d001]: “\r\n\r\n\r\n\r\n \r\n \r\n”

We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved.

I am not sure what has caused this all of a sudden and have tried following the suggested troubleshooting guide that is linked in the error message, but have not had any luck. Any suggestions?

Fyi, I am using name.com and not Netlify DNS

Hi @philbriceno,

You’ve an AAAA record that’s blocking the provisioning:

Removing that record did the trick. For future reference, how did you know that was blocking it? Honestly, I am not sure why that record was even there.

Thank you for the help!

As a rule of thumb, AAAA records don’t work with external DNS (at the moment). So you would either have to use Netlify DNS or remove the records
