http:ListenAndServe() not listening in GoLand w/Debugger

I am starting my first Go app using GoLand. I have used PhpStorm since it was in beta so am familiar with JetBrains IDEs.

I am trying to build a simple HTTP server using the code from this article and I have it working when I run the app from the terminal command line:

However when I run from within GoLand it immediately exists after calling http.ListenAndServe().  What do I need to do to get it to stop and listen to allow me to debug the request handler?



As soon as I asked I found my own answer. Seems that the app was running in the background and blocking access to the port.
