I had the same problem and the answer was "V1 WebServer template. This template must be added to your CA server." not allowed. But after running the command on the command line:
certreq -submit -attrib "CertificateTemplate:WebServer" request.req
My request was a process, and my certificate was issued to me. In addition, I got a βSelectβ button that works great.
