@maryamariyan Yes, it seems to be the same issue:
WinHttp.WinHttpQueryDataAvailableinSystem.Net.Http.WinHttpResponseStream.CopyToAsyncCoreending withError 12030 calling WINHTTP_CALLBACK_STATUS_REQUEST_ERROR, 'The connection with the server was terminated abnormally'So far failing methods are (according to Kusto):
GetAsync_AddCookieHeader_CookieHeaderSent GetAsync_AddMultipleCookieHeaders_CookiesSent GetAsync_ReceiveInvalidSetCookieHeader_ValidCookiesAdded GetAsync_ReceiveSetCookieHeader_CookieAdded GetAsync_ReceiveSetCookieHeader_CookieUpdated GetAsync_SetCookieContainer_CookieSent GetAsyncWithRedirect_ReceiveSetCookie_CookieSent GetAsyncWithRedirect_SetCookieContainer_CorrectCookiesSentAll above only for
System.Net.Http.Functional.Tests.PlatformHandlerTest_Cookies_Http2.
I'll disable allPlatformHandlerTest_Cookies_Http2forWinHttpHandlerin this PR: #34119Reacted by Karel ZikmundLooking at @ManickaP's traces with help from the WinHttp team we found out that the (loopback test) server closes the connection (sends FIN) before the client has chance to process the data -- in which case WinHttp discards all buffers, causing this test failure.
