Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA.

So, I was trying to create a SSL certificate with certbot…..

root@sd-5555:~# certbot --apache -d blog.domain.com

This was how I’v done to properly create it.

certbot --authenticator standalone --installer apache -d blog.domain.com --pre-hook "systemctl stop apache2" --post-hook "systemctl start apache2"

Your computer has expired certificates.
To solve this make the following actions:

    b) Category: Certificates
  3. Scroll each certificate and if it has expired delete it.
