Azure support for TLS 1.0 and TLS 1.1 will end by 31 October 2024

Question

I have an Azure App Gateway that requires TLS 1.0 to be enabled for legacy applications, will client apps be able to connect to the App Gateway after 10/31/24? Does this scenario apply to Azure web apps, where the legacy client is connecting with TLS 1.0?

Answer 1

Yes it applies to web apps. After this date, these versions will be out of support and possibly unable to connect, including for Azure Application Gateway and Azure App Services.

If your legacy applications require TLS 1.0, they will no longer be able out of support after the deadline. To maintain connectivity, you will need to upgrade your applications to support TLS 1.2 or higher.

To avoid potential service disruptions, confirm that your resources that interact with services are using TLS 1.2 or later. Then:

• If they're already exclusively using TLS 1.2 or later, you don't need to take further action.
• If they still have a dependency on TLS 1.0 or 1.1, transition them to TLS 1.2 or later by October 31, 2024.
