I set up a pull server and a couple of clients, following the guidelines in the DSC book, but the client's don't appear to be able to connect. I see these errors in the log:
This event indicates that failure happens when LCM is trying to get the configuration from pull server using download manager WebDownloadManager. ErrorId is 0x1. ErrorDetail is Cannot download configuration from http://:8080/PSDSCPullServer.svc. Downloading over HTTP is not allowed.
Checking the IIS logs on the pull server the requests are not reaching the server.
Note that the url shows up as a link in the event viewer, clicking the link will pull up the web service in IE. These requests I do see in the IIS logs on the pull server.
I have verified that the URL and settings for DownloadManagerCustomData are correct:
