Fix “TLS protocol strength” on nginx
Allow only TLS 1.2 and 1.3; disable TLS 1.0/1.1 and weak ciphers.
ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers off;
Verify the fix
Re-run the TLS protocol strength check after deploying. Test config changes in staging first and keep a rollback: a wrong header can break a site faster than a missing one.
