When WSUS is installed on a Windows Server 2016 (or higher), it may happen that the server cannot obtain updates from itself as a source and therefore reports the error code “0x80246010”.
The issue can be resolved either via a GPO or via a registry entry.
GPO
Computer Configuration\Policies\Windows Components\Windows Update
Add the value “Set the alternate download server” in “Specify intranet Microsoft update service location”.
Registry
Path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Type: String Value
Name: UpdateServiceUrlAlternate
Value: http://WSUS-NAME:8530
