To solve this error, before running the certbot, I’v stopped the httpd(s) server(s) and it worked! 😉
/usr/bin/certbot certonly –standalone -d www.playboy.com –preferred-challenges http

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"
