I am using mattermost-docker latest version. I want to config tls 1.2 for web container. Currently my mattermost instance supports TLS 1.0 and TLS 1.1. Grade limit to B.
cert.pem chain.pem fullchain.pem key-no-password.pem
The certifying authority is Let’s encrypt.
How to config to support also tls 1.2 and obtain Grade A?
