Cannot display webpage after updating SSL Certificate

May 6, 2014 by Chris Sanchez

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:

 C:\>certutil –repairstore my “‎1a 1f 94 8b 21 a2 99 36 77 a8 8e b2 3f 42 8c 7e 47 e3 d1 33”

 certutil repair

 Note: 1a 1f 94 8b 21 a2 99 36 77 a8 8e b2 3f 42 8c 7e 47 e3 d1 33 is the thumbprint of the certificate. Open the certificate and click on the details tab. Scroll down to find the thumbprint section. 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:

If the association is successful, then you would see the following window:
