получая 12030 на WinHttpReceiveResponse

Я только что начал использовать SSL с winhttp. Я получаю ERROR_WINHTTPCONNECTION_ERROR

в MSDN документы, на которых написано: 

The connection with the server has been reset or terminated, or an incompatible SSL protocol was encountered. For example, WinHTTP version 5.1 does not support SSL2 unless the client specifically enables it.

В чем может быть причина? Я пробовал разные ссылки.

gcc myFile.c -o myFile.exe -lwinhttp это аргумент.

          }

      } while (dwSize>0);


  // Report any errors.
  if (!bResults)
      printf("Error %d has occurred.\n",GetLastError());

  // Close any open handles.
  if (hRequest) WinHttpCloseHandle(hRequest);
  if (hConnect) WinHttpCloseHandle(hConnect);
  if (hSession) WinHttpCloseHandle(hSession);

}

Нужен ли мне дополнительный файл или что-то? Я на windows 10.

Вы пропускаете флаг WINHTTP_FLAG_SECURE при вызове WinHttpOpenRequest. Этот флаг необходим для HTTPS.

Вместо этого: 

    hRequest = WinHttpOpenRequest(hConnect, L"GET", L"/en-us/windows/win32/debug/system-error-codes--1000-1299-",
        NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, NULL);

Это: 

    hRequest = WinHttpOpenRequest(hConnect, L"GET", L"/en-us/windows/win32/debug/system-error-codes--1000-1299-",
        NULL, WINHTTP_NO_REFERER, WINHTTP_DEFAULT_ACCEPT_TYPES, WINHTTP_FLAG_SECURE);

Когда я добавил этот флаг, ваша программа, кажется, работает.
