git - ssh_exchange_identification: Connection closed by remote host 报错

Question

github is inexplicably unable to push code,

Error report:

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

Regenerate the ssh key according to the official documentation. And execute ssh -T git@github.com after adding it. Error:
ssh_exchange_identification: Connection closed by remote host

The code to execute ssh -vT git@github.com is as follows:

$ ssh -vT git@github.com
OpenSSH_6.9p1, LibreSSL 2.1.8
debug1: Reading configuration data /etc/ssh/ssh_config

Here/Users/yangzhongjing/.ssh/id_rsa this file exists. I don’t know why it reports: key_load_public: No such file or directory

I searched a lot online and tried the following methods but to no avail:

• vim /etc/hosts.allow Add sshd: ALL

• ssh-add ~/.ssh/id_rsa

• Adjusted the /etc/ssh/sshd_config in MaxSessions 10 to make it bigger

• Delete ~/.sshDirectory and regenerate ssh key
