I am attempting to setup DSC Pull and Target Servers. The Pull Server part seems functioning well as I can successfully browse to the https:\…PSDSCPullServer.svc/$metadata and receive the XML file.

I am now attempting to register the target but am finding errors in the output and on the DSC Pull Server’s Event Log. The Event log error says:

> The client with raw URL /PSDSCPullServer.svc/Nodes(AgentId='9167A3EA-3674-11E7-80D4-000D3A34F962') has invalid protocolversion header specified. Supported ProtocolVersion is 2.0.

Here is the entire script : [Failed Registration of DSC Agent with Server · GitHub](https://gist.github.com/Chiliyago/7fcc05b4c3ed439c9d5ab86c5954f581)

Is this a bug or am I doing something wrong?

P.S. I am using WMF 5.1 on Windows Servers 2012 R2

I take it that the ssl cert for the securer Pull Server is issued by [dc1.MyDomain.com](http://dc1.MyDomain.com)? If so does the node have the trusted root cert for that cert authority on it if not it will not trust the SSL cert.

Yes I can see the certificate in the ‘Trusted Root Certificate Authorities’ on the target node. I am able to browse to the URL and get no certificate warnings which leads me to believe I have the server and certificate portion of the equation configured correct.
