WS_E_PROXY_ACCESS_DENIED
WS_E_PROXY_ACCESS_DENIED is a Windows Web Services API HRESULT. It means that the proxy refused the request because of an access rule, authentication requirement, content policy, destination restriction, or similar proxy-side control.
What to check for WS_E_PROXY_ACCESS_DENIED
- Check proxy authentication, destination allow-lists, user identity and policy logs.
- Confirm that the endpoint URL and transport are allowed for the account and network segment.
- Correct the proxy policy or request configuration instead of silently routing around the proxy.
Diagnostic interpretation
This result has the HRESULT value 0x803D0016. AllStat records the condition as “Access was denied by the HTTP proxy server.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the ws / proxy / access / denied operation.
- check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.
