I'm using dotnet core sdk 2.0 SPA template for angular. when running the application, i can see following error. This issue is there when it running through visual studio 2017 as well as when it published to azure.
But when i switch off the pre-rendering by removing asp-prerender-module="xxx", it is working fine.

WinHttpException: The connection with the server was terminated abnormally

IOException: The read operation failed, see inner exception.
