flask server

Based on your clarifying comments, it appears your browser is accessing a previous version of your app server.

I have run into this problem myself when using the PyCharm IDE. On Windows, the way to shut down these old versions of the server is to press either Ctrl+Alt+Delete or Ctrl+Shift+Esc (Windows 10) to view your list of running processes. Then scroll down until you see processes named Python and shut them all down.

flask server

I don't know if it's due to some other python application running or something, but when I was a beginner in Flask I got a similar error to you.

I wrote app.route('/') instead of @app.route('/') (I missed the @ symbol).

See whether it's the case for your code.

flask server

You should have written @app.route('/home/'). That fixed the problem for me!
