Error: The pending certificate request for this response file was not found.

Solution ID:    SO5992    Updated:    04/04/2012


This problem may occur if any of the following conditions are true:
  • The certificate file is formatted incorrectly or the wrong extension file is being used for the installation
  • A private key mismatch may occur if the private key in Microsoft IIS does not match the certificate you are installing
  • The private key for this certificate has been corrupted, lost, or this is not the server on which the CSR was generated
  • You used the previous CSR upon Renewal
  • The wrong certificate file is being used for the installation


Because there are many causes for this error, please review the methods below and determine which is applicable: 
Method 1: Ensure Proper Formatting of the Certificate File  
Copy and paste the certificate into a text file (save as .txt) using Vi or Notepad. Do not use Microsoft Word or other word processing programs that may add characters. Confirm that there are no extra lines or spaces in the file. You should have a text file that looks like:
[encoded data]
Make sure you have 5 dashes to either side of the BEGIN CERTIFICATE and END CERTIFICATE and that no white space, extra line breaks or additional characters have been inadvertently added.
 Method 2: Ensure the SSL Certificate Matches the Private Key on Microsoft IIS  
Ensure that you do not delete the pending request or generate another CSR in Microsoft IIS after you have submitted the CSR to GeoTrust.
When you generate a CSR, this creates a private key that corresponds to the CSR file. If you delete the pending request and/or generate a new CSR, the existing private key is replaced with the new one. Therefore, when you try to install the SSL certificate, it will not match to the private key.  
Method 3: Reissue the Certificate Due to File Corruption or Deletion  
If you cannot install the file because of corruption or because the original Pending Request was deleted and another was created in its place, you must generate a new certificate request and perform a reissue.
To reissue your certificate please follow the instructions in solution: SO5989
Method 4: Use of the previous CSR file upon Certificate Renewal  
Microsoft IIS 5.0/6.0 will not allow the installation of a SSL certificate without a matching pending request. If you have renewed your SSL certificate and selected the option to use the previous CSR, you will not be able to install your certificate using the IIS Certificate Installation Wizard. Therefore, you will need to create a renewal request from IIS and then reissue your certificate. 
To create a renewal request for IIS 5.0/6.0, see Step A in solution: SO12639

To reissue your certificate please follow the instructions in solution: SO5989
