Versions being used?

powershell v5 April preview (on the pull server and on the node)

I’d suggest enabling diagnostics on both machines, and then trying again, and seeing if anything better showed up in the Diagnostics logs.

not to much info

i get on the node dsc event log ,error 4404 and 4252

With nothing else to go on, I’d probably install and try a new pull server with the client, as a test.

I tried it and got the same error

maybe its HTTPS related?

a BUG ?
