Specified certificate doesn't contain private key

I have implemented GroupDocs.Signature for .net trial version. It is running fine in my local visual studio as well as IIS but when I am hosting it on another machine(windows server) it is giving an error “Specified certificate doesn’t contain private key” . I am using the same certificate in both environments. It would be very helpful to have a fix for this issue.


Please share following details and we’ll investigate this scenario:

  • API version (e.g. 20.1, 20.9) that you’re evaluating
  • Sample code
  • Source document and certificate file
  • Server details/information
