WU_E_PT_SOAPCLIENT_SEND
WU_E_PT_SOAPCLIENT_SEND is commonly a wrapper around a lower-level WinHTTP send failure. The decisive information is normally the accompanying or preceding WinHTTP HRESULT.
How to investigate
- Inspect the Windows Update log for the specific WinHTTP result, such as proxy authentication or DNS resolution failure.
- Check whether a proxy, firewall, or TLS inspection device blocks or alters outbound requests.
- Verify that the system WinHTTP configuration matches the required update path.
netsh winhttp show proxy
