When you login to Azure try the following:

App Services > Web App > App Service logs > Detailed Error Messages.

What error messages are you receiving there?

What kind of web app did you create? Many of them might not have a default page, where you need to modify the web server settings (IIS or others) so that the default page can be located when / is accessed. Without that, the error message you saw (403.14) is expected.

As you revealed enough details on this issue, I think the cause is also clear. Not sure from where did you get an out-of-date guide to publish this Python web app to Azure App Service (Windows), but it is no longer supported by Microsoft.

You can find the statement "Linux is the only operating system option for running Python apps in App Service. Python on Windows is no longer supported." in https://learn.microsoft.com/en-us/azure/app-service/configure-language-python

To learn how to deploy it to App Service (Linux) you can refer to the tutorial here, https://learn.microsoft.com/en-us/azure/app-service/quickstart-python?tabs=flask%2Cwindows%2Cazure-portal%2Clocal-git-deploy%2Cdeploy-instructions-azportal%2Cterminal-bash%2Cdeploy-instructions-zip-azcli

Hi Lex, Thank you for the inputs I have used linux OS for the web app task in azure devops pipeline. Looks like It is working now. Please see following

However can you please clarify even I used .py code to deploy in the above web app why it is showing default web app. Thank you.

Seeing the default page is a step forward. To troubleshoot further you might follow https://learn.microsoft.com/en-us/azure/app-service/configure-language-python#app-doesnt-appear and the next step is "If your files exist, then App Service wasn't able to identify your specific startup file. Check that your app is structured as App Service expects for Django or Flask, or use a custom startup command."
