app.route not working in workspace

In workspace when I add '/newroute' to the address I keep getting 404. The code works fine on my machine though.

from flask import Flask

app = Flask ( __name__ )

@app.route('/newroute')
def index():
  return "Hello from Treehouse"  

app.run(debug=True, port=8000, host='0.0.0.0')

Firstly, you forgot the two dunders (Double underscore) before and after name.

app = Flask(__name__)

Second of all, because the route has a name, in this case its is called '/newroute', you must specify the route in the browser as well.

@app.route('/newroute') 
def index(): 
    return "Hello from Treehouse"

Hope this helps!

Thanks for the reply! Of course I have dunders, somehow they disappeared after copy-pasting the code. Thank you for noticing, I will edit the question. And sure I add /newroute to the address.
