I have used Certbot in order to produce certificates for two of my sites. The sites are hosted on a VPS server. I have SSH access and plesk. The problem is that my plesk version is older from version 12.5 so the plugin is not supported. I tried installing it.
I used certbot in order to create certificates with letsencrypt for my two websites. It seems that the process completed successfully but still my old (invalid) certificates are in place. Plesk has functionality to manually import certificates but I was unable to find which files from /etc/letsencrypt/ should be copied into the fields required by Plesk’s default certificate functionality.
Any help would be appreciated.
