MVC application under NGNIX rule to run application with virtual directory URL

Question

I have MVC 5 application which is running on IIS on this URL http://localhost:8080. I want to get it run by appending some text in the url like http://localhost:8080/app. To achieve this I have done below things.

1. Setup Nginx server to redirect url for /app

   server   {
                  listen       8080;
                  server_name  localhost;
                  location /app
                  {
                  proxy_pass   http://localhost:8084/;
                  } 
        }
   

2. Created directory structure on server like this C:\intepub\Test\app

3. Created application under Test folder on IIS like below.

   IIS
   --Test (Virtual Directory)
   -- app (as web application under Test) --This is in asp.net MVC5

After doing all this steps when I run the application using url http://localhost:8080/app it didn't worked and getting below exception:

HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable
