家里网络如下：
➜ ~ curl cip.cc
IP: 1.84.212.163
地址: 中国 陕西 咸阳
运营商: 电信
数据二: 陕西省西安市 | 电信
数据三:
URL:
无论如何无法访问
但是ping 是OK的
浏览器和命令行访问都是报：
➜ ~ curl -I
curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to www.jianshu.com:443
幸好，自己本地起了sockets 代理：
如下操作：
➜~ curl -I --socks5-hostname 127.0.0.1:7070 HTTP/2 200 server: Tengine content-type: text/html; charset=utf-8 date: Tue, 20 Oct 2020 07:48:55 GMT vary: Accept-Encoding x-frame-options: SAMEORIGIN x-xss-protection: 1; mode=block x-content-type-options: nosniff etag: W/"002fb68ab23dcf6790b0aa26bd" cache-control: max-age=0, private, must-revalidate set-cookie: locale=zh-CN; path=/ x-request-id: 82b04bda-1861-448b-a75b-dd0f x-runtime: 0. strict-transport-security: max-age=; includeSubDomains; preload via: cache40.l2nu20-2[70,0], cache5.us8[739,0] timing-allow-origin: * eagleid: 2ffe所以配置Safari的代理，其实是配置的网络的代理
关于sockets代理如下配置的：
/usr/local/bin/autossh -M 12345 -qTfnN -D 7070 xule@IP地址
再访问www.jianshu.com就OK了
暂时解决了。后期看下什么原因？
因为虚拟机里面的Centos主机是可以直接请求到的。同局域网的IOS设备也无法访问。难道是
简书的Tenginx做了特殊设置？歧视？
浏览器报错：

命令行下典型报错
➜ ~ curl -I /p/c5fa45312f5b
