I was recently looking into an error for specific WSUS clients which were unable to find updates on the WSUS server reporting the following error message:
Failed to find updates with error code 80244019
On investigating the log file (C:\Windows\WindowsUpdateLog.log) on one of the affected clients I could see that the send request to the WSUS server was failing and that the SelfUpdate check failed to download the package information, as below:
Misc WARNING: WinHttp: SendRequestToServerForFileInformation failed with 0x80190194 Misc WARNING: WinHttp: ShouldFileBeDownloaded failed with 0x80190194 Misc WARNING: DownloadFileInternal failed for http://<server name>/selfupdate/wuident.cab: error 0x80190194 Setup WARNING: SelfUpdate check failed to download package information, error = 0x80244019 Setup FATAL: SelfUpdate check failed, err = 0x80244019
It would appear that the WSUS server had been upgraded and the original TCP port used for client connectivity was no longer in use. As the Windows Update configuration of the clients is managed via Group Policy this required the update location to be modified to include the updated URL following the TCP port change to 8053, as below:
Setting Path: Computer Configuration>Policies>Administrative Templates\Windows Components\Windows Update Setting: Specify intranet Microsoft update service location. State: Enabled Options: Set the intranet update service for detecting updates - http:<server name>:8530
Once the update to the configuration had been applied and the group policy setting refreshed, the client was able to download and install approved updates from the WSUS server.
