Check if the server certificate has the private key corresponding to it. Refer the below picture:

SSL Cert wo and wprivate key

If private key is missing, then you need to get a certificate containing the private key, which is essentially a .PFX file. There is a command that we could try to run in order to associate the private key with the certificate:

Select the thumbprint section and click on the text below. Do a “Ctrl+A” and then “Ctrl+C” to select and copy it. Below is a snapshot for your reference:
