Remediation

From Azure Portal

1. Login to Azure Portal using https://portal.azure.com.
2. Go to App Services.
3. Click on each App.
4. Under Setting section, Click on Configuration.
5. Set HTTP version to 2.0 under General settings.

NOTE: Most modern browsers support HTTP 2.0 protocol over TLS only, while non-encrypted traffic continues to use HTTP 1.1. To ensure that client browsers connect to your app with HTTP/2, either buy an App Service Certificate for your app's custom domain or bind a third party certificate.

From Azure CLI

To set HTTP 2.0 version for an existing app, run the following command:

az webapp config set --resource-group <RESOURCE_GROUP_NAME> --name <APP_NAME> --http20-enabled true

From PowerShell

To enable HTTP 2.0 version support, run the following command:

Set-AzWebApp -ResourceGroupName <app resource group> -Name <app name> -Http20Enabled $true
