Hello folks,
I have run into a problem after an update with our base image that we use when deploying new servers with DSC.
After the update I get this error:
Job {DFB1E732-49DF-11E7-90FC-001DD8B736E9} : WebDownloadManager for configuration 5fe70830-f941-4c05-975f-b43909398e55 Do-DscAction command, GET call result: FullyQualifiedErrorId :WebDownloadManagerGetActionFailed CategoryInfo:InvalidResult: (:) [], InvalidOperationException ExceptionMessage:Failed to get the action from server https://[PULLSERVER]/PSDSCPullServer.svc/Action(ConfigurationId='5fe70830-f941-4c05-975f-b43909398e55')/GetAction. , InnerExceptionSystem.AggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
And the error message that follows is that the client thinks there is no partial configurations availible on the pull server.
As it says there are som certificate issue. But I can´t figure out what’s the problem with that certificate.
Both client and pull server is running on Server 2016 and with latest wmf 5.1. When im trying with an older image that have not been patched recently every thing works great.
I’m woundering if Microsoft have changed som requirements during the last two month or if someone else is having the same issue.
Side note - both client and pull server is fully patched (May-patch) and with the latest modules on the pull server.
