Use client SSL cert to secure panel?

[deltatech]

My control panel uses the same domain name as my website which is stored under a client/subscription. How can I use this same SSL certificate used for my website to secure the panel?

Go to admin panel -> Tools & Settings -> SSL certificates and add your certificate once again. Then select added certificate and click the button "Secure the Panel".

This does not work on my Linux server I still get an error when trying to upgrade the Plesk version

Secure Connection Failed







An error occurred during a connection to eateasy.co.uk:8447.

Peer's Certificate has been revoked.

(Error code: sec_error_revoked_certificate)

Any thoughts
