GitHub に ssh で接続できなくなりました。

**~/.ssh/config**

[code]

    Host github.com
      User git
      Hostname github.com
      IdentityFile ~/.ssh/鍵名
      Port 443
    
[/code]

**実行ログ**

22ポートだと下記が表示され、タイムアウトになってしまいます。

[code]

    XXX@YYY .ssh %  ssh -vT  git@github.com       
    OpenSSH_8.1p1, LibreSSL 2.7.3
    debug1: Reading configuration data /Users/XXX/.ssh/config
    debug1: Reading configuration data /etc/ssh/ssh_config
    debug1: /etc/ssh/ssh_config line 47: Applying options for *
    debug1: Connecting to github port 22.
    
[/code]

色々調べたのですが、わからず、どなたかに解決策をご教示いただきたいです。
