Disappearing SSL Certificates

Disappearing SSL Certificates

So, your SSL Certificate disappears when attempting to “Complete Certificate Request” on IIS8?

I had the same issue. We needed to reissue our SHA-1 certs to SHA-2 certs so we received the certificates, and then I followed the directions from Geotrust Premium for IIS8 for installing the certificate.

There are two important items to be aware of:

1. The SSL Cert has to be in PKCS#7 format
2. Be sure to install the intermediate certificate.


For the SSL Cert, if you received an email with the “—–BEGIN CERTIFICATE—–” section, that will probably be in the wrong format. You will have to download the PKCS#7 format, which you can do by requesting to view the order information.

I did make some mistakes along the way and missed the part of using PKCS#7 format, which probably caused my issue. The problem I was having is when I tried to complete the certificate request on IIS8, the SSL certificate would disappear and there would be no error message. After some digging and reviewing the Certificate snap-on for the MMC console tool on Windows 2012 I learned that the Private Key was not generated correctly. I eventually found an article on Geotrust that showed how to rebuild the private key, then I was able to successfully complete the certificate request. Hopefully, this will help others from avoiding a few hours of trying to figure out the problem.
