SSL certificate is not installing

I'm facing an issue in installing SSL certificate in IIS and below are the step before I got the certificate from my CA.

  1. Generated a private key file using OpenSSL with: "openssl genrsa -out key_name.key 2048" command.

  2. Generated .csr file with: "openssl req -out CSR.csr -key key_name.key -new -sha256" command.

  3. Once I generated the CSR file, I provided the same CSR file to CA to get me certificate.

  4. I got the certificate in .p7b format, which I converted to .cer format.

  5. Installed certificate using "Complete certificate request" option in IIS.

Now the problem is that newly installed certificate vanishes from IIS after a refresh. I Googled this issue and understood that, it's happening so because there is no private key associated with certificate. My question is where the private key has gone?? I had created the CSR using the private key in step 1. Secondly, how do I over come this issue, I have to install the certificate anyhow. Please help.

You did not generate the certificate request via IIS Manager. Thus, you should not use IIS to complete the request.

Instead, you need to use OpenSSL to generate a PFX file,

create a pfx file from a .cer and a .pem file

Then you can import it to IIS.
