How to open localhost:8080 in Cloud9 IDE?

Question

I am developing an app engine project (golang) in Cloud9 IDE. For testing in desktop i would go to localhost:8080 in my desktop browser.

In Cloud9, I tried https://workspace-username.c9.io with $PORT set as 8080, but somehow its not working for appengine project. But it is working for normal go web project though.

How do i test app engine application in Cloud9 IDE? or

How do i open http://localhost:8080 in Cloud9 IDE?
