When trying to access Parallels Power Panel or Parallels Infrastructure Manager, the following error is shown in the browser:

Secure Connection Failed
An error occurred during a connection to cinderella:4643.
You have received an invalid certificate.  Please contact the server administrator or email correspondent and give them the following information:

Your certificate contains the same serial number as another certificate issued by the certificate authority.  Please get a new certificate containing a unique serial number.
(Error code: sec_error_reused_issuer_and_serial)

You may generate your own SSL certificate and install it into the Service Container; it will be used by Power Panel (Virtuozzo Power Panel in Virtuozzo 3.x or Parallels Power Panel in PVC 4.0) and Virtuozzo Control Center (VZCC) or Parallels Infrastructure Manager (PIM) panels.

The following link describes how to create certificates:

There is no need to do this inside the Service Container on the Virtuozzo node; any machine with OpenSSL installed is good. When you have both the certificate and private key, you can put them into the default files:

/etc/httpd/conf/ssl.key/server.key (private key)
/etc/httpd/conf/ssl.crt/server.crt (certificate)
Alternatively, you can define your own location for the key/certificate pair in the /etc/vzcp/httpd.conf file inside the Service Container.

It is necessary to restart services for the changes to take effect:

# service httpd restart

# service vzcp restart

Also, you may used the attached script to generate a PIM SSL certificate and install it inside the Server Container.
