Backing Up Certificates in Plesk
Plesk stores SSL related files in a "httpd.pem" file inside a "cert" folder. Both the RSA private key and certificate are kept inside the
"/home/httpd/vhosts/domain.com/cert/httpd.pem" file.
Back up the RSA private key from this folder.
Check your certificate installation for SSL issues and vulnerabilities.
