WU_E_PT_HTTP_STATUS_DENIED

WU_E_PT_HTTP_STATUS_DENIED maps to HTTP 401: the requested resource requires authentication. Determine whether the challenge comes from WSUS, a reverse proxy, or an outbound proxy before changing credentials or policies.

What to check

Identify the component returning the 401 by checking server and proxy logs for the request time.
Verify that the system context used by Windows Update is allowed to access the configured service path.
Do not rely on a browser test alone because Windows Update uses WinHTTP and may use different proxy credentials.
