git - ssh_exchange_identification: Connection closed by remote host 报错

Question

github 莫名无法 push 代码，

报错：

fatal: unable to access 'https://***.git/': SSL peer handshake failed, the server most likely requires a client certificate to connect

重新按照官方文档生成ssh key。并添加后执行 ssh -T git@github.com 报错:
ssh_exchange_identification: Connection closed by remote host

执行ssh -vT git@github.com代码如下：

$ ssh -vT git@github.com
OpenSSH_6.9p1, LibreSSL 2.1.8
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 21: Applying options for *

ssh_exchange_identification: Connection closed by remote host

这里面/Users/yangzhongjing/.ssh/id_rsa 这个文件是存在的。不知道为什么会报：key_load_public: No such file or directory

网上搜了很多执行了以下方法都没有效果：

• vim /etc/hosts.allow 添加 sshd: ALL

• ssh-add ~/.ssh/id_rsa

• 调整了 /etc/ssh/sshd_config 中的 MaxSessions 10 调大

• 删除 ~/.ssh目录重新生成ssh key
