I’m running a Flask application inside a Vagrant virtual machine. The app is set to listen on all addresses (0.0.0.0), and I can access it from within the VM using curl http://localhost:5000. However, I cannot reach it from my host laptop’s web browser. I get a “This site cant be reached” error.

below is the code i used

from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return "Congratulations! Flask is running successfully."

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)

and when i run it, i get

vagrant@ubuntu-focal:~/smart-home-project$ python3 app.py

• Serving Flask app ‘app’
• Debug mode: off
  WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
• Running on all addresses (0.0.0.0)
• Running on http://localhost:5000
• Running on http://Vm-ip:5000
  Press CTRL+C to quit

i get the error when i paste http://Vm-ip:5000 on my browser

I confirmed that the Flask app is running correctly and accessible from the VM.
I tried changing the port to 8000
i tried disabling firewall on both Vm and the laptop

I was hoping that with this, i’d be able to load it on my browser but the error still persist
