Hurdle in launching a Flask application on AWS Lightsail
The original project code is on VS Code. Pushed the application's image repository to DockerHub.com and from there pushed to AWS Lightsail.
Here is the status on Amazon CLI:

Unable to figure out why nothing loading on http://127.0.0.1:5000. Since the static IP address for this instance is 44.206.118.123, also tried with http://44.206.118.123. But blank page.
If access to app.py file or any other files such as requirements.txt/DockerHub needed in order to troubleshoot, I will provide. Not providing just now for the sake of brevity.
The above project is just for display and not mission critical. As of now, my goal is to make the project live (can be viewed by anyone using the url or IP address).

Hello,
I would recommend to check that your Flask app config app.py is configured to run on all network interfaces (0.0.0.0) and on the correct port (5000).
if __name__ == "__main__":
app.run(host="0.0.0.0", port=5000)
You can follow this tutorial to deploy Flask application to Light Sail: https://aws.amazon.com/tutorials/serve-a-flask-app/
http://44.206.118.123:8080/ Same source code on AWS Lightsail (Ubuntu) showing internal server error once the form submitted though working fine on VS Studio (https://www.canva.com/design/DAGIZJrhyIk/EYzsYG5sfXMmEazS77EQ1w/edit?utm_content=DAGIZJrhyIk&utm_campaign=designshare&utm_medium=link2&utm_source=sharebutton).
