To cancel a renewal means that the certificate will not be renewed anymore. The
certificate, bindings and other configuration that is already in place will not
be touched, so it’s completely safe to do this without disturbing your
production applications. Only you will have to set up a new renewal or
alternative certificate solution before the certificate reaches its natural
expiration date.
You can cancel a renewal from the main menu. The program will then delete the
.json file from disk and forget about it.
