I have a successfully working https website for which I have applied to the certificate using a web-form. Now there is an intranet webclient which I have not included in the initial certificate. I want to use the certbot to locate the existing certificate, which is under /etc/ssl/certs and expand the certificate so I can add the new intranet domain. However when I type in certbot certificates, I receive a no certificates found error.
Is it not possible to use certbot to locate existing certificates, which were not obtained by certbot?
Thanks
