ping 可以访问，但是 curl 和 wget 都不可以，会是什么原因

[twofox]

项目需要访问单点认证的网址 单点认证那边是没问题的，防火墙也是开的，其他地方没有做限制的了

# curl -v https://login.XXX.com/XXX/login -4
* About to connect() to login.jxcia.com port 443 (#0)
*   Trying 117.XX.XX.X...
* Connection refused
* Failed connect to login.XXX.com:443; Connection refused
* Closing connection 0
curl: (7) Failed connect to login.XXX.com:443; Connection refused

ip addr 输出了很多的虚拟网卡，有没有可能跟这个有关

[tomemi]

看看路由和防火墙

[twofox]

@tomemi 防火墙全关，路由也不会有限制的

[newaccount]

这里试了下，不加路径的二级域名是可以的。看返回头，隐藏了 nginx 版本，考虑是不是人家在服务器配置了 UA 检测？你改个浏览器的 UA 试试呢？

[tomemi]

@twofox #2 抓包

[aaa5838769]

telnet 看下端口通么。

[twofox]

@newaccount 单点服务也是我司的。。不会限制


@tomemi 有点为难我这个 CURD Boy 了

[twofox]

@aaa5838769 不通，就这一个地址不通，要是换成其他的域名。例如百度啥的，都是通的

[cnit]

你直接用 ip 加端口不走 nginx 试试

[fengci]

你是不是本地 hosts 了

[Routeros]

http_proxy?

[cnit]

# 拒绝 User-Agent
if ($http_user_agent ~* LWP::Simple|BBBike|wget|curl) {
return 444;
}
反正我们这有这个

[twofox]

@fengci 没有

@cnit 不行

[cnit]

你怕不是在命令行里面加了代理

[twofox]

@cnit 不可能的，系统会崩掉

[motherfaka]

telnet 不通，curl 其他网站通，大概率是服务端口的问题

[cnit]

额 我反正之前闹过这样的乌龙，其他的我想不到了 ，你可以试试在命令行里面能不能 curl google 或者 youtube 确认下

[motherfaka]

拿自己电脑测了一下，telnet 是通的，curl 也是通的，那还是客户端网络的问题……

[julyclyde]

refuse 不可能是 nginx 的功能
nginx 开始处理的时候都已经 accept 完毕了

[lhbc]

1. 云厂商的防火墙
2. 域名备案

[twofox]

@lhbc 本地机房，备案完善
