What does HRESULT 0x80072EFE (WININET_E_CONNECTION_ABORTED) mean?

WININET_E_CONNECTION_ABORTED

What WININET_E_CONNECTION_ABORTED means

WININET_E_CONNECTION_ABORTED (0x80072EFE) means the WinINet connection with the server was terminated abnormally before the request completed.

The code identifies a broken connection, not a unique root cause. The remote peer can close the connection, an intermediary can terminate it, or the local network/WinINet path can lose the transport. A firewall, proxy, TLS device, server process, or network interruption is relevant only when evidence places the close at that layer.

Evidence to preserve

• The WinINet API that returned the error and the related HINTERNET object hierarchy.
• The destination host and path, selected proxy route, redirect/authentication stage, and request timing without logging credentials.
• The first transport/TLS/proxy error or callback state that precedes 0x80072EFE.
• Whether the server or intermediary closed an established connection, or the client lost connectivity before a response was received.

Recovery

Correct the layer that actually terminated the connection. Retry is reasonable after connectivity or server state changes, but repeated requests alone do not distinguish a remote close from a local proxy or transport problem.
