不知道什么情况，今天远程 4 台 vps 都会出现这个问题。然后阿里云的可以，并且从阿里云 ProxyJump 也是可以的。 这种情况，应该怎么办？

百度热搜 1 中国主要城市成美网络秘密入侵目标。不知是不是高墙发威了，再加上今天演习打台湾？

ssh 原生支持代理的，我从来都是用代理用 ssh,毕竟代理线路可以非常好，主机不一定很好。

我现在都是 ProxyCommand cloudflared access ssh --hostname %h 的，稳如老狗

-vvv 之后的显示应该是这样的，估计没收到响应
debug3: send packet: type 20

debug3: receive packet: type 20

用 https://tcp.ping.pe/测试一下你这些服务器的 22 端口是否绿色状态，至少你日志中的服务器 22 端口全部可连通的。

mac 电脑用手机热点试试，如果 4G/5G 网络没问题，说明你宽带有阻断
