我的nginx confid文件看起来像：

server {
   listen          80;
   listen [::]:80;

   server_name hostserver.ru www.hostserver.ru;
   return 301 https://hostserver.ru$request_uri;

   server_tokens off;
  }

 server {
   listen 443 ssl http2;
   listen [::]:443 ssl http2;
   server_name     hostserver.ru www.hostserver.ru;

   ssl_certificate /etc/letsencrypt/live/hostserver.ru/fullchain.pem;
   ssl_certificate_key /etc/letsencrypt/live/hostserver.ru/privkey.pem;
   ssl_dhparam /etc/ssl/certs/dhparam.pem;
   ssl_session_timeout 1d;
   ssl_session_cache shared:SSL:50m;
   ssl_session_tickets off;
   ssl_protocols TLSv1.2;
   ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-R$
   ssl_prefer_server_ciphers on;
   add_header Strict-Transport-Security "max-age=31536000" always;
   ssl_stapling on;
   ssl_stapling_verify on;

   root /var/www/html;
   index index.html index.htm;
   server_tokens off;

   ... some location stuff...
}

不幸的是，TLS1.2不支持Android 4.0-4.3，我已经chanched配置：

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

但是在使用SSLTest之后，它显示我报告TLS 1和TLS1.1不受支持。
我错过了smth更改配置文件吗？提前感谢。

**更新：**我已通过以下命令检查证书：

openssl s_client -tls1 (and so on) -connect example.org:443 < /dev/null

以及为每个协议启用的证书。
