Came across an issue recently where after a reboot we were unable to access our IIS site via it’s https address with the following error in Internet Explorer ‘Page Cannot be Displayed’
In the application event log we had the following ‘Schanel error’.
Event ID 36870
A fatal error occurred when attempting to access the SSL server credential private key. The error code returned from the cryptographic module is 0x8009030d. The internal error state is 10001.
This error occurs when you import your certificate into the ‘Certificates (Local Computer)’ personal store by dragging and dropping it from the the ‘Certificates – Current User’ personal store.
To get around this issue you have to import directly to the ‘Certificates (Local Computer)’ personal store and then apply this certificate to the IIS https binding and reboot.
Then your HTTPS site should all be working again
