Hello All

I created a web app using the ASP.Net Core Web App template which works fine in VS2022 on my laptop.

I uploaded it to a shared hosting windows server and now its crashing.

Symtoms;
1, It responds to 10 to 15 requests then performs a reload of the page, just like old style ASP.NET post back then shows a blank screen and sometimes error 400

I managed to get. the log working and below is the output . I am a hobbyist and late coming to .net core, So help would be great. Thanks
