why can't I access flask app root URL from my web app?

Question

I have a deployed application that seems to be functioning correctly. Upon inspecting the shell logs, I can confirm that the app is running and listening on the specified port. It's also successfully handling incoming requests. However, I'm encountering an issue where the root URL is not functioning as expected. Interestingly, the same code works flawlessly when run locally. I've checked the traffic settings, and there don't appear to be any restrictions in place. I'm perplexed as to why this discrepancy exists. Any assistance in troubleshooting this matter would be greatly appreciated.

Hi,

It seems like the static files are not being served properly.Ensure that you have defined a route for the root URL ("/") in your Flask application. This is typically done using the @app.route('/') decorator in your Flask application code.

Here's an example:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return 'Hello, World!'

if __name__ == '__main__':
    app.run()

Once you have made the changes, you can redeploy your app and try accessing the image again.

Let me know if this helps!
