LPTHW Ex50: "http://localhost:8080" not found

Greetings!
I’m have just started the LPTHW Ex50, I typed in the app.py and ran it as instructed it shows the expected result:

http://0.0.0.0:8080/

But after when I go to the http://localhost:8080 as mentioned in the book I Get this:

Error

This is my app.py file:

import web

urls = (
    'http://localhost:8080', 'index'

)

app = web.application(urls, globals())

class index:
    def GET(self):
        greeting = "Hello World"
        return greeting
    
    if __name__  == "__main__":
        app.run()

What am I doing wrong?

(I’m on Windows 7 with Powershell & Editor is VSC with Chrome as Browser)

I resolved this issue by myself, Apparently the link must be opened from the Default Browser :sweat_smile:
