Как настроить SSL на NGINX, чтобы получить оценку A в ssllabs.com?

Question

[Дмитрий]

Добрый день! Пытаюсь настроить nginx в debian, чтобы получить хотябы ранк A в ssllabs.com, сейчас у меня оценка C. Причина:
No support for TLS 1.2, which is the only secure protocol version

Конфиг Nginx:

server {
        listen 443 ssl;
        server_name site.ru www.site.ru;
        root /var/www/site;
        charset utf8;
        index index.php;
        error_log /var/log/nginx/site.log crit;
        ssl_stapling on;
        ssl on;
        ssl_session_timeout 10m;
        ssl_session_cache shared:SSL:2m;

        ssl_certificate /etc/nginx/lr-ssl/site.crt;
        ssl_certificate_key /etc/nginx/lr-ssl/site.key;
        ssl_dhparam /etc/nginx/lr-ssl/dhparams.pem;
        ssl_protocols TLSv1.2 TLSv1.1 TLSv1;

            expires 3d;
        }

У меня тоже WoSign, dhparam.pem генерил, набор шифров тот же... но всё равно только по TLS 1 соединяется. Куда копать?

[Артём Липовка]

покажите apt-cache depends nginx

[Дмитрий]

Артём Липовка: Depends: libc6
Depends: libpcre3
Depends: libssl0.9.8
Depends: zlib1g
Depends: lsb-base
Depends: adduser

Подозреваю, что либы опенссл должны быть другими

[Артём Липовка]

Depends: libssl0.9.8

Артём Липовка: Отлично! Спасибо, Артём. Помогло, сейчас A+, обновил openssl до 1.0.2g, но проблема была в nginx и его старой зависимости от libssl0.9.8!

Классная вещь, спасибо, но не помогло... у меня где-то похоже nginx глючит с openssl

У меня не выходит с подобными параметрами. Всё так же C. Но ещё больше замечаний выдаёт. Порядок следования инструкций в конфиге ведь не важен?
