Web App (Linux) - BadGateway/Forbidden - The subscription is not allowed to create or update the serverfarm

Question

I am having trouble creating a new Web App (Linux) for my client. My client owns the Microsoft/Azure tenant, and my account has been added as a co-administrator.

I have been able to create Azure Function apps, and also a PostgreSQL Flexible server for this client. But I have not been able to create an App Service - Web App (Linux) yet, because I keep getting an error that reads "BadGateway": Forbidden. The subscription '********************' is not allowed to create or update the serverfarm.

Configuration for the web app:

• Name: (was available)
• Publish: Code
• Runtime stack: .NET 8 (LTS)
• Operating System: Linux
• Region: mostly West US, but I tried a whole bunch (see below)
• Linux Plan: (New)
• Pricing Plan: Basic B1
• Zone redundancy: Disabled
• All other tabs were left at their defaults

Some things I have tried so far:

• Double checking the billing account: credit card is loaded and we are on a Pay as you Go plan.
• Deploying to different regions: I have tried every region in the USA. Also tried Central Canada. No luck.
• Having my client use their Microsoft 365 admin account to deploy the web app: they got the same error.
• Deploying using a different Resource Group: no luck
• Re-registering the Microsoft.Web resource provider with my subscription: no luck
• Disabling application insights: no luck

I am out of ideas--any help would be appreciated! Thanks in advance :)

Answer 1

This is a known issue, and is likely due to a backend delay enabling the Microsoft.Web resource provider.

You'll need to wait up to 24 hours and try again.

If the issue persists then open a support request with Microsoft.
