Duplicate certificate limits - is the private key generated?

Hi, we’ve had a few domains hit the duplicate renewal limit due to a bug in our application. It appears the certificate was generated by checking crt.sh, but as limit means our configuration didn’t complete the process, we did not receive the certificate/private key. Is there a manual way to retrieve the private key? If so, where can it be found?

The ACME client generates the private certificate locally in order to submit a CSR to Let’s Encrypt.

if you don’t have the private key saved, then it’s impossible to retrieve.

If you’re using Certbot, you can look in /etc/letsencrypt/keys to see if one matches, but you’ll have to manually test them against the certificates to find out which, if any, match.


Thanks, that makes sense. Will check via your suggestion
