The error 80131509 appears when you attempt to import the updates from Microsoft Update Catalog into WSUS. This error can be resolved by setting the registry value SchUseStrongCrypto to 1 on the server.

To globally modify the available cryptographic protocols for all .Net applications (versions 4 and above), just enable “strong cryptography” on the Windows registry. If strong cryptography is disabled, only SSL 3.0 and TLS 1.0 will be used for secure connections. Otherwise, TLS 1.0, TLS 1.1, and TLS 1.2 will be used.

To set the SchUseStrongCrypto registry value to 1 in the registry on the WSUS server, perform the following steps:

  1. Open a CMD on the WSUS server as Administrator.
  2. Enter the following command: reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319 /V SchUseStrongCrypto /T REG_DWORD /D 1
  3. Validate that the key was successfully created in Registry.

If the above command doesn’t work for you, here is how you manually create the SchUseStrongCrypto key in the registry and set a value 1 for it. Launch the registry editor by running the command “regedit.” In the Registry Editor, navigate to the following path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319. Right-click v4.0.30319 folder and select New > DWORD (32-bit) Value.
