WININET_E_CONNECTION_RESET

WININET_E_CONNECTION_RESET means that an established connection was reset while WinINet was using it. The result does not prove which side caused the reset; it can originate from the remote server, an intermediary, or a local network device.

What makes the error actionable

  • Record whether the reset happened before a response, during body transfer, or while reusing a persistent connection.
  • Record the request method, whether the request body was fully sent, and any proxy or TLS endpoint in use.
  • Correlate with server and proxy logs by time and request identifier where available.

Retry policy

A new request may be safe for idempotent operations when the application can determine that the server did not apply the request. Do not automatically replay a non-idempotent request when its delivery or processing status is unknown.
