When you create a certificate, the private key (.key), certificate signing request ( csr) and certificate (.crt) files are all generated. These files need to be associated with the site on the local machine where the server is running. You are not allowed to create certificates while remotely administering because these files need to be available to the server on the local machine where the server is running.
If you want to use a certificate while remotely administering the server, you need to have already created or imported certificates on the local machine.
If you are remotely administering and know the path to a certificate on the local machine, you may associate that certificate with a site.
