Problem with the renewal of the certificate

Good morning,
having to renew the certificate now expired, I found myself with this error:
Attempting to renew cert from /etc/letsencrypt/renewal/ produced an unexpected error: urn: acme: error: rateLimited :: too many failed authorizations recently: see Skipping.
Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.

To perform the renewal, first in: cd / etc / letsencrypt,
and by root launch the command: certbot -q renew --apache.

I already thank those who will help me.

Hi @Matteo

do you use a wildcard certificate? If yes, you have to use dns-01-validation.

Or your certbot should be updated.


well, I tried to update certbot with the usual command but I failed,
do you have any other ideas to update it?

no it is not a wildcard.

Thanks so much

What does Certbot output if you run “certbot renew” or “certbot -q renew”?

Unfortunately the error you pasted isn’t the helpful one - it’s just telling us there were too many failed attempts in the past hour. If you try again now, you’ll probably get a different one that will give us more information about what’s actually failing. If you get the same rate limited error, give it bit and try again, the failed validations limit is a rolling window of sixty minutes, so it shouldn’t take too long to clear up.

with the certbot renew command I get this error:

  • The following errors were reported by the server:

    Type: connection
    Detail: Connection reset by peer

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A record (s) for that domain
    contain (s) the right IP address. Additionally, please check that
    your computer has a publicly routable IP address and that no
    firewalls are going to be the server from communicating with the
    client. If you’re using the webroot plugin, you should also verify
    that you are serving files from the webroot path you provided.

My boss has warned me now that the management of site domains has recently been handed over to another company, and that we only manage the website. could this be the problem?

Thanks again a thousand

Looks like you can't connect the website. What's your domain name?
