HTTP 404 not found means that the WebAPI action method could not be found based on the URL given.  Yiu can use Postman free that will help you debug. What web client or HTTP client software are you using to access the WebAPI?

Hi,

You followed something such as https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/?view=aspnetcore-2.1 ?

If this is your first deployment you could perhaps enable static file and try with a test.htm page to see if is configured properly. For now technically speaking the incoming url doesn't hit anything that would know how to respond to this resquest.

This an ASP.NET Web API or ASP.NET Core Web API? 

What exactly did you upload as ASP.NET Core requires a proxy.  Does your host provider support ASP.NET Core?

Your response is too vague to guess what you've uploaded.  I specifically asked what you uploaded because manually deploying ASP.NET Core requires a few steps extra steps other than simply uploading files.  It is not clear if you followed these steps.

Did you read and follow the openly published deployment documentation posted above?

https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/?view=aspnetcore-2.1&tabs=aspnetcore2x

Can you explain clearly and accurately how you deployed the ASP.NET Core 2 application?  Have you verified your hosting provider supports ASP.NET Core?

I asked becasue it you manually deployed the application is 

Right, that's the problem.  It seems that you made up your own deployment strategy without reading the deployment instructions.   

This is the third time we're presenting the link.  Please read the instructions.
