Trouble switching from a manual to regular cert

So, I don't see the "congratulations" message here, but rather an error (in this case possibly related to IPv6: you have an AAAA record advertising an IPv6 address for your site, but it might not be configured in the same way as the IPv4 address).

Is it possible that you misinterpreted the output of your previous --apache command as a success? That seems likely to me because you have only ever issued one valid Let's Encrypt certificate for your domain

which I assume is then the --manual one rather than a subsequent --apache one.

The command that you used does change the default behavior, but only when the certificate is successfully issued.

One thing to investigate might be the IPv6 issue. In the future, you might also encounter a different issue using --apache with your current version of Certbot:

However, it seems that this issue didn't arise for you in this case because renewals of previously-issued certificates, when using the same Let's Encrypt account ID, are exempt.
