I use Debian 12. To get a certificate for my domain, I did everything according to the instruction for Debian 10 here Certbot Instructions | Certbot
I got the certificate successfully, but the dry-run renewal fails with the following output:
Failed to renew certificate bcservers.org with error: Unable to register an account with ACME server. Error returned by the ACME server: error checking key quality
All simulated renewals failed. The following certificates could not be renewed:
/etc/letsencrypt/live/bcservers.org/fullchain.pem (failure)
Nothing. Think you are probably getting the same http error 500 as another person just reported. I can also reproduce the problem. Hopefully staff will provide status about this soon
This problem should be resolved. Like the others, it was caused by the database being unavailable -- we have a database table of bad keys which must be consulted.
