I have installed the Let’s Encrypt plugin to Plesk on a Windows 2012 server. I am having a hard time figuring out how to add additional domains to get an SSL certificate for in the Plesk interface. I only see one and it’s for the server name itself, not for any of my domains. I set my domains/websites up outside of Plesk through IIS, so that may be the issue.
I am a bit of a newbie, so apologies if this is something obvious.
