“We currently support TLS versions 1.0, 1.1, and 1.2. Setting a minimal TLS version ensures that subsequent, newer TLS versions are supported. We recommend setting the minimal TLS version to 1.2, after testing to confirm your applications support it, because it includes fixes for vulnerabilities found in previous versions. It’s also the highest TLS version supported in Azure Database for MySQL.”
