ACME now uses ZeroSSL, here is what you need to do for your CyberPanel

ACME now requires your e-mail to be registered first this is simple just go to your SSH and use below command to register your e-mail with ACME & ZeroSSL.

acme.sh --register-account -m [email protected] --server zerossl

After its registered you need to use CyberPanel or below command to issue SSL for your website, change example.com to your domain.

/root/.acme.sh/acme.sh --issue -d example.com -d www.example.com --cert-file /etc/letsencrypt/live/example.com/cert.pem --key-file /etc/letsencrypt/live/example.com/privkey.pem --fullchain-file /etc/letsencrypt/live/example.com/fullchain.pem -w /home/example.com/public_html --debug

or below if you don't want to debug

/root/.acme.sh/acme.sh --issue -d example.com -d www.example.com --cert-file /etc/letsencrypt/live/example.com/cert.pem --key-file /etc/letsencrypt/live/example.com/privkey.pem --fullchain-file /etc/letsencrypt/live/example.com/fullchain.pem -w /home/example.com/public_html --debug

If you want to keep using Letsencrypt use this:

/root/.acme.sh/acme.sh --set-default-ca --server letsencrypt
