Overview

You want to enforce the highest level of TLS only and disable all weaker SSL and TLS versions and want to know if ListManager can operate with just TLS 1.3.

Information

ListManager has certain limitations when it comes to web traffic over TLS. If you want to force TLS 1.2 or higher you will need to implement a reverse proxy externally to ListManager. See the Enforcing TLS 1.2 or 1.3 in Lyris LM Through an Nginx Reverse Proxy article for details and a downloadable implementation guide.
