100 Days of Cloud (Azure)- Day 31: Azure Lab Issue – Unable to Create Required Web App - xfusion-webapp

Hello Team,

I am working on the Azure lab that requires creating a Python web application with the following specifications:

Web App Name: xfusion-webapp
Region: South Central US
Runtime: Python on Linux
App Service Plan: xfusion-learn-python (Basic B1)

I successfully logged into the provided Azure subscription and created the App Service Plan:

Resource Group:
kml_rg_main-dfadfaa7ee094125

App Service Plan:
xfusion-learn-python

However, I am unable to create the required web app because Azure reports that the name already exists.

Verification performed:

No web apps exist in the subscription:

az webapp list

Result: Empty

Resource inventory:

az resource list --output table

Result:
xfusion-learn-python | Microsoft.Web/serverFarms

Name availability check:

Response:
“nameAvailable”: false
“reason”: “AlreadyExists”

Direct ARM API creation attempt:

Error:
Website with given name xfusion-webapp already exists.
Code: Conflict
ExtendedCode: 54001

This suggests that the hostname xfusion-webapp is already registered in another Azure subscription/tenant and cannot be created in the lab subscription.

Could you please verify whether the lab environment needs to be reprovisioned or whether there is a known issue with this exercise?

Thank you.

Could you please refer to this post?
