- Make sure the certificate you added to "Server Certificates" is the one you created a "Certificate Request" for. If you add a certificate that wasn’t requested in "Server Certificates", it won’t show up in IIS binding window even if it does in "Server Certificates" list
- Make sure there is a private key in the certificate (steps are below)
Check if the certificate has a private key:
- Open mmc. Add Certificates for Computer account
- A "key image" should be on the certificate image. You can also check it by double clicking the certificate
If the certificate doesn’t have a private key, run the command below.
certutil -repairstore my [thumbprint]
You should see CertUtil: -repairstore command completed successfully message. Close IIS Manager and open it again. Then check if the certificate appears in the binding window.
