socket.gaierror: [Errno 11001] getaddrinfo. Flask app was working a week ago and now I'm seeing this error. not sure what is going

Flask app that I run on windows I have not changed any since it was last functioning. and now I'm seeing this error which I don't understand why its occuring.

Trackback when I try to run the app:

 flask run -host=0.0.0.0

From flask docs:

If you have the debugger disabled or trust the users on your network, you can make the server publicly available simply by adding --host=0.0.0.0 to the command line:

So use --host instead of -host:

flask run --host=0.0.0.0
