WU_E_REDIRECTOR_SLS_GENERIC_ERROR
WU_E_REDIRECTOR_SLS_GENERIC_ERROR is a Service Locator Service (SLS) redirector failure. It covers both a connection problem and a response-parsing problem, so the log sequence is needed to separate them.
What to check
- Check DNS, proxy, TLS, and HTTP results immediately before the code appears.
- Verify that system-level WinHTTP proxy settings are correct; Windows Update can use a different path from an interactive browser.
- Confirm that policy does not intentionally block the connection to public update locations.
netsh winhttp show proxy
Microsoft: Windows Update proxy selection
Microsoft: Manage additional Windows Update settings
