title: Gitlab - Too many authentication failures for git
body: <p>My command line git is not working since last week, all I remember is that I init a local folder into git version controlled, and add a remote git ref to it. Then my git is unable to push or pull. It shows:</p>
  
  <pre><code>git clone git@gitlab.xxx.com:xxx/myproj.git myproj
  Cloning into 'myproj'...
  Received disconnect from 192.168.xxx.xxx: 2: Too many authentication failures for git
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  </code></pre>
  
  <p>What's weird is that my version control in JetBrain Idea works fine, it can still pull or push that project which can't be pull in command line.</p>
  
  <p>I've add the id_rsa.pub to gitlab before, and I re-add it again now, but it does not work.</p>
  
  <p>My ssh debug info</p>
  
  <p>ssh -v git@gitlab.xxx.com</p>
