Hello there,

If you are getting Error Code 1312, the certificate you are attempting to bind likely does not contain the private key. If you are getting Error Code 1312, you can determine if the certificate you imported contains the private key by looking at its icon in MMC

Make sure you've installed the certificate in the service account (MMC -> add snap-in -> certificates -> computer account) and NOT in your personal account.

The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.https://social.technet.microsoft.com/Forums/windowsserver/en-US/68452008-a89b-40ba-9927-472efcfafc99/ssl-certificate-add-failed-error-1312

Hope this resolves your Query !!

I had the same error. The first time it occurred, I had to move the certificate under the Certificates(Local Computer) -->Personal -->Certificate folder. I had the same error when I imported the same certificate on another machine. The reason was that I was using certmgr.msc to import the certificate. The window opened thus shows “Certificates – Current User”. Certificates imported using this window cause netsh to fail with the 1312 error. Make sure to use certificate snap-in in MMC to import certificates. The certificate snap-in from MMC shows “Certificates (Local Computer)”.
