404 When Uploading Large File How to Fix Iis

Question

I can't get my ASP .NET web app running on my new AWS EC2 VM Windows Server 2016. Spider web app has been running on Azure VM Windows Server 2012 R2 for years.

THE PROBLEM:
I go:

"Mistake 404 - File or directory not plant"

..when I try to browse from external Net, or on the server itself, to my ASP.NET web app hosted on Windows Server 2016 IIS on a new AWS EC2 VM. Same error if I browse from IIS > Sites > my web site > Manage Website > Scan

When I remove and re-add together web site, I become this error (also run into screen shot below):

IIS > Add together Website > Test Connection > yellow warning sign Cannot verify access to path(path to my spider web app projection)

ATTEMPTS TO FIX...
IIS > Connections > my_web_site > browse doesn't work: "The webpage cannot be constitute"
IIS > Connections > my_web_site > Manage Website > browse cmd gets Server Mistake 404 file or dir not institute
IIS > Connections > my_web_site > Edit Bindings > browse gets Server Error 404 file or dir not found

I tried deleting IIS > Sites > my web site and then re-adding it. All the same go mistake 404.

BACKGROUND...
ASP.Net works ok on previous Azure VM Windows Server 2012 R2.
ASP.Internet app runs ok when I debug it from Visual Studio on new AWS VM.
All IIS bindings set upwards simply like on previous Azure VM.
