Introduction
During a Certero tenant upgrade, after multiple successful tasks there is a problem with the Configure website task. The error “A specified logon session does not exist. It may already have been terminated. ((0x80070520) [ConfigureBindings]” is shown.

Don’t panic, the upgrade has been successful. Starting the Certero platform and Endpoint services will make the tenant accessible once again.
The cause of the error was the manual binding of a SSL certificate to the Assetstudio_<tenant-id> website within Internet Information Services (IIS) Manager. The matching of a Certero tenant to an SSL certificate should be done with Certero Provisioning and not separately in IIS.
Instructions
Connect to the Certero Provisioning website (servername:9000).
Choose tenants
Against the appropriate tenant click

(actions) and choose Configure.
On the Website tab, under SSL Certificate select the CN (Common Name) of the certificate you want this tenant to use.

Click Save and then Yes to the temporary loss of service warning.
Ensure the task lists complete successfully.

N.B. Future tenant upgrade should complete without the error message.
Remember the following:
Cererto Component Website | SSL Certificate |
Provisioning (Certero Provisioning Services) | Manually BIND via IIS |
Platform (AssetStudio_<tenant ID> | Provisioning (as described above) |
Standalone Endpoint Server (Default Web Site – CerteroEndpointServer) | Manually BIND via IIS |
