Application could not run on port 5000

[mgthantzin]

I have cloned the repo and run the app. Port 8080 works fine with dotnet run command or F5 in VS Code but port 5000 doest not work. Hence, Fetch data page has exception message.

However, if I run the solution in Visual Studio, everything works just fine. Fetch data works, too.

What am I missing?

Edit: I am following the steps outlined here.
