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.
My domain is: https://www.osafar.com
I ran this command: certbot --apache -d osafar.com -d www.osafar.com -d cupchai.com -d www.cupchai.com
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache
You have an existing certificate that contains a portion of the domains you
requested (ref: /etc/letsencrypt/renewal/osafar.com.conf)
It contains these names: osafar.com, www.osafar.com
You requested these names for the new certificate: osafar.com, www.osafar.com,
Do you want to expand and replace this existing certificate with the new
certificate?
