Clone code from Github to EC2 server in nginx

ubuntu@ip-172-31-90-199:~$ git clone https://github.com/vimlesh-verma16/Instagram_clone_FastAPI.git
ubuntu@ip-172-31-90-199:~$ cd Instagram_clone_FastAPI
ubuntu@ip-172-31-90-199:~/Instagram_clone_FastAPI$ ls
Notes  README.md  __pycache__  db  main.py  requirement.txt
ubuntu@ip-172-31-90-199:~/Instagram_clone_FastAPI$ sudo apt install python3.12-venv -y
ubuntu@ip-172-31-90-199:~/Instagram_clone_FastAPI$ python3 -m venv env
ubuntu@ip-172-31-90-199:~/Instagram_clone_FastAPI$ source env/bin/activate
(env) ubuntu@ip-172-31-90-199:~/Instagram_clone_FastAPI$ pip install -r requirements.txt
(env) ubuntu@ip-172-31-90-199:~/Instagram_clone_FastAPI$ python3 -m uvicorn main:app

After doing all this steps.
Now, open http://54.21.32.23 (your EC2 Public IPv4) in a browser.
❌ DO NOT use https://, as Nginx is listening on port 80 (HTTP).

Successfully deployed the FastAPI on EC2 !!!!!
