Hi MS-experts,

I'm developing an application which is using HttpClient to communicate with the REST APIs. But sometimes, I'll get the the exception code in my log.

I don't understand what these two error codes mean.

0x80072EFE
0x80072EE4

Best Regards,
Steven

    From C++ headers :

    0x80072EFE = WININET_E_CONNECTION_ABORTED

    0x80072EE4 = WININET_E_INTERNAL_ERROR

    0x80072EFE ERROR_WINHTTP_CONNECTION_ABORTED The connection with the server was terminated abnormally

    0x80072EE4 ERROR_WINHTTP_INTERNAL_ERROR An internal error occurred in the Microsoft Internet extensions

    The first error usually caused by networking, or when the remote side closed the application/connection abruptly. There is little thing you could do with it, so we'll generally ignore them.

    The second one is usually caused something wrong in WinINet stack, say something prevent it to write to cache folder or else. Maybe you can check Event Viewer and see if there is more clues.
