WININET_E_NOT_PROXY_REQUEST

WININET_E_NOT_PROXY_REQUEST is a WinINet HRESULT. It means that a request or configuration operation requiring a direct WinINet session was attempted through a session configured for proxy access.

What to check for WININET_E_NOT_PROXY_REQUEST

  • Inspect the access type and proxy settings used when the parent Internet handle was created.
  • Use a handle configured for the required direct or proxy operation instead of changing behavior mid-request.
  • Check organization proxy policy before bypassing a proxy to work around the error.

Diagnostic interpretation

This result has the HRESULT value 0x80072EF4. AllStat records the condition as “The request cannot be made on a Proxy session”.

Evidence to capture

  • Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the wininet / proxy / request operation.
  • Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original wininet / proxy / request condition.

Retry and recovery

Retry this result only when the owning API documents a transient state or after the condition described as “The request cannot be made on a Proxy session” has changed.
