我的 nginx confid 文件如下所示：

 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，Android 4.0-4.3 不支持 TLS1.2，我更改了配置：

   ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

但是在使用SSLTest …

我正在尝试通过openvpn连接到我们的学院VPN.当openvpn运行时,我从openssl得到以下错误

使用OpenSSL 1.1.0时不会出现此错误这些错误出现之间的变化是什么？ …
