I cannot connect to flask API no matter what method i try. I have a seperate jupyter notebook as a host to my flask app, i also have my NLP model backend in my jupyter notebook. everytime i try to test my given API on Postman it just wont connect, furthermore all the link given just wont connect with the message cant reach this page. ***.0.0.1000 wont connect. I really need this API to work so i can connect to my frontend android studio to my backend jupyter notebook
