@Kesavamurthi D , Apologies for any inconvenience with this issue and my delayed response from over the weekend.

Have you observed this behavior since the Webapp first deployment or started seeing this more recently?

Do you recall making any changes prior to this issue?

You may review and checkout the following information.

If application.py

gunicorn
--bind=0.0.0.0 --timeout 600 application:app

If app.py

gunicorn --bind=0.0.0.0 --timeout 600 app:app

use a different name for the app object, or you want to provide other arguments to Gunicorn, use a custom startup command.

By default, the App Service on Linux container assumes that a Flask app's WSGI callable is named app and is contained in a file named application.py or app.py resides in the app's root folderolder.

Kindly let us know if you're still experiencing this issue. For deeper investigation on this, we would need more information about your WebApp.

@Kesavamurthi D , Thanks for the follow-up and additional info. As I understand you have raised a support request already, could you please share the #SR ID, I'll follow-up on this internally, which would help us perform deeper investigation.
