Install the certificate with Plesk Server Administrator

You are here:

Important: The installation is a two-step process - make sure you follow the two steps below.

Step 1: Upload your SSL certificate

In PSA, select the domain in which you are installing the SSL certificate.
Access the domain's SSL area by clicking the Certificate button.
When a CSR (Certificate Signing Request) is generated, there are two different sections of text, the RSA Private Key (which you received from Plesk by email) and the Certificate Request. When installing a certificate, the RSA key for the private key must be inserted in the block in front of the web server site certificate.

Example:

—– BEGIN RSA PRIVATE KEY —–
[[ENCODIERTER TEXTBLOCK]]
—– ENDE RSA PRIVATE KEY —–
—– BEGIN CERTIFICATE —-
[[ ENCODIERTER TEXTBLOCK]]
—– END CERTIFICATE —–

Paste the private key with the certificate text into the Enter certificate Text: text box and press the Send text button.

If successful, a message is returned with the message "Certificate successfully installed".
If errors occur, the old certificate will replace the new certificate you just sent to the server and you will need to enter it again. Now click on "Up Level" to return to the "Domain Administration" page.

Step 2: Upload the rootchain certificate

You must install the Intermediate CA certificates so that browsers can trust your certificate. The certificates of the intermediate certification authority are in the " ca-bundle " file that was attached to your email in the * .zip file that we sent you (this should be " yourSERVERNAME.ca-bundle are called ).

In PSA, select the domain in which you are installing the SSL certificate.
Access the domain's SSL area by clicking the Certificate button.
The icon next to Use rootchain certificate for this domain will appear on this page .
If the symbol is [ ON ], the rootchain certificate for this domain is activated. If the symbol is [X], it is deactivated.

Make sure the icon is [X] before proceeding (you may need to click the ON / OFF button if the icon is set to [ON]):
