How can I upgrade the version of TLS on an application running in app engine to > 1.2

[Faber Lombard]

I am running an Angular app inside app engine. Recently this application was PEN tested and one of the issues that came up was around TLS1.0 and TLS 1.1 in use.

The recommendation from these results are to disable all TLS protocols before TLS1.2. Only use cipher suites considered cryptographically strong.

The application presently doesnt have a custom domain and is purely hosted on .appspot.com

How do I achieve this? Would I need to use a custom domain for this? I've tried read around but feel a little out of my comfort zone with this.

Thanks

Hello Faber,

You may make a request to disable weak ciphers by creating a Google Issue Tracker using this link. We will follow up with you then.
