服务器停留在SSL，客户端响应后进行TLS握手

Question

需要解决方案，

服务器有时会在发出请求时卡住。请求：

SSLCertificateFile /etc/apache2/ssl/cert.crt
SSLCertificateKeyFile /etc/ssl/private/cert.key
SSLCACertificateFile  /etc/apache2/ssl/cert.ca-bundle

我的证书：

<VirtualHost *:443> 
ServerName asd.com 
ServerAlias asd.com 

<Directory /var/www/html> 
  Options Indexes FollowSymLinks MultiViews 
  AllowOverride All 
  Order allow,deny 
  allow from all 
  Require all granted 
</Directory> 

ServerAdmin webmaster@domain.com 
DocumentRoot /var/www/html 

SSLEngine on 
SSLCertificateFile /etc/apache2/ssl/cert.crt 
SSLCertificateKeyFile /etc/ssl/private/cert.key 
SSLCACertificateFile /etc/apache2/ssl/cert.ca-bundle 
</VirtualHost>

虚拟主机配置：
