Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
I ran this command:
certbot renew --pre-hook “systemctl stop apache2” --post-hook “systemctl start apache2” --renew-hook “systemctl reload spache2; systemctl reload dovecot; systemctl reload postfix”
It produced this output:
