Server runs in terminal but doesn't appear in the page. Serving Flask app "application" (lazy loading)

Question

Serving Flask app "application" (lazy loading)
Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead.
Debug mode: off

@application.route('/', methods=['POST', 'GET']) @application.route('/') def default():

Originally, running python application.py works - the page appears but after a while of doing the same thing, the web page doesn't appear anymore and instead the warning above shows in my terminal. What is the problem?

Any chance you could share the startup portion of the app code? And are you running Flask via the command line, or via an IDE debugger? — ingernet, Nov 29 '19 at 23:47

" While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well and by default serves only one request at a time. "

I also found this: warning message while running flask

If you search with the warning/error message you get, you will find questions that were already answered.
