Trouble with Subordinate CA - Unable to submit CSR

I have a Subordinate CA running on Windows 2016 Server - its been issuing certs until recently where I am now only ever getting the error when trying to submit a CSR:

The request contains no certificate template information.
0x80094901 (-2146875391 CERTSRV_E_NO_CERT_TYPE)
Denied by Policy Module 0x90094801,
The request does not contain a certificate template extension of the CertificateTemplate request attribute

Any help appreciated.

EDIT:

Web Server is a listed Certificate Template under my CA Certificate Templates

I worked on this for an hour today and just figured out that "Web Server" was not a valid template and I was supposed to use "WebServer". A-r-r-rg!
