@systemadmin, @serverco is right: if the certificate was created originally using manual, then the renew command can’t work on it (because renew is designed to work without human intervention, while manual always requires human intervention). So indeed, getting a new certificate using a non-interactive method would be best, if your situation would allow for that. If you need help with that process, we’d be happy to help, but we’ll probably need some more information about your setup in order to understand what would be likely to work for you.
