The SSL certificate used by Parallels Plesk Panel has expired. How can it be renewed?

  • Parallels Plesk for Linux/Unix
  • Parallels Plesk for Windows


When Parallels Plesk Panel control panel or another site is opened via HTTPS, a warning is displayed regarding an expired certificate.

How do you renew it?


Please note that installations of Plesk 7.x, 8.x, and 9.x are compatible with Offline Management of PVA Power Panel and connections to the port 8443 can be served by services on the hardware node. If this is the case (the URL contains "/vz/cp/"), then follow the steps described in the KB article How do I install SSL certificate for Power Panel or PVA Management Node?.

There are no special Plesk certificates provided by Parallels. The default SSL certificate you used for the Parallels Plesk Panel is a self-signed certificate, which is generated once during Plesk installation. The SSL certificate presence is required for SSL connections.

This is a default certificate shown in the server certificate repository at Server -> Certificates (for Parallels Plesk Panel 7.5, 8.x) and at Settings -> SSL Certificates (for Parallels Plesk Panel 9.x).

You can create your own self-signed certificate on the Certificates page or purchase a real certificate from one of the world certificate authorities.

To create a new self-signed SSL certificate, log in to Parallels Plesk Panel as an administrator. Go to the Certificates page and create a new certificate.

For Parallels Plesk Panel version 7.x, 8.x:

Server -> Certificates -> Add New Certificate

For Parallels Plesk Panel version 9.x:

Settings -> SSL Certificates -> Add SSL Certificate

For Parallels Plesk Panel version 10.x:

Tools & Utilities -> SSL Certificates -> Add SSL Certificate

For Parallels Plesk Panel version 11.x & 12.x

Tools & Settings -> SSL Certificates -> Add SSL Certificate

Fill in the required preferences and click the button {Self-Signed}.

A new self-signed SSL certificate will be created in the server certificate repository.

To assign this SSL certificate for securing your Parallels Plesk Panel, check the new enabled SSL certificate in the list and click on Secure the panel if you have Plesk 8.2 or later. Or click Install if you have an older Plesk version.

Also you can use HTTP mode to access the panel: http://hostname:8880 and follow the same instructions as mentioned above.

Renew is also possible through SSH:

  1. Connect to Plesk server under root.

  2. Go to certificate directory and rename it:

    # cd /usr/local/psa/admin/conf/
    # mv httpsd.pem{,.old}
  3. Create a new certificate with the same name:

    # openssl req -new -nodes -x509 -out httpsd.pem -newkey rsa:2048 -keyout httpsd.pem -days 3650

    and fill all required fields.
    In this case a certificate with PEM type will be created, valid for 10 years with a private part without password and 2048 bit key length.

  4. Restart sw-cp-server:

    # /etc/init.d/sw-cp-server restart

Also, see Plesk documentation for how to set up self-signed certificates.

After you have created or uploaded a new certificate into Plesk and wish to use it for domains, you should set it for every IP you need so that the domains use it when you access them via HTTPS.

This can be done via page Server -> IP Addresses -> "choose IP" by selecting the needed Certificate in the "SSL Certificate" drop-down menu.
