Remediation

From Azure Portal

1. Log in to the Azure portal using https://portal.azure.com.
2. Go to App Services.
3. Select each app.
4. Under Settings, select Configuration.
5. Set HTTP version to 2.0 under General settings.

Note: Most modern browsers support HTTP 2.0 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 {{resource-group-name}} `
    -Name {{app-name}} `
    -Http20Enabled $true
