Unable to deploy ML model on aws using EC2 instance

I have created an EC2 instance and created a new folder . Cloned my github repository into the new folder created. Ran the main.py fastapi file on ubuntu EC2 terminal. Assuming the model is executed as there is no error message popped up  Iam using the IP4 address to check whether the model is running or not . But,when i tried to open the url its showing 404 detail not found . Kindly refer to the snapshot below
