我大概在一两个星期前就能访问该网站。最近，无论我使用什么浏览器，计算机或设备从网络内部访问dmv.ca.gov，SSL握手都会失败，并且该站点将给出空响应。我可以访问其他站点，包括ca.gov，但不能访问dmv.ca.gov。我认为握手失败，因为服务器没有响应。
当我从ubuntu框中运行openssl时，得到以下输出：
captain@HARM01NGINX01:~$ openssl s_client -state -nbio -connect dmv.ca.gov:443 -servername dmv.ca.gov

但是，我期望的是以下内容（对我拥有的AWS实例使用相同的命令：

DIG给我相同的dns记录，所以我知道我正在连接到正确的服务器。
在这一点上，我的想法不多了。所以，我问大家，我接下来可以看什么或进行测试？
我有Verizon提供的actiontec路由器，我需要检查该设备上是否有任何设置。
