The Problem: You attempt to install (or renew) an SSL certificate in Plesk (web hosting management software) but when you follow the instructions (meaning add the certificate in Plesk, and then going to the “Setup” screen for the domain, you do not have the option of selecting the renewed certificate.
The Cause: This is the first domain that was created and an SSL cert was immediately added, then other domains were added via Plesk. Plesk no longer sees this domain as having a valid IP address it can use. There is no way to change this in Plesk.
The Solution: Bypass Plesk and install directly in IIS – go to this link on installing an SSL cert and follow the directions very carefully.
