title: Cannot setup ssh keys on my github account
body: <p>I generated ssh keys in ~/.ssh folder and added those keys to my github account but when I run the following command to test my ssh connection 
  <code>$ ssh -T git@github.com</code>
  I get the following error:
  <code>ssh: connect to host github.com port 22: Connection timed out</code>
  I am not able to understand the error here.</p>
  
  <p>I added ssh key in my github account going into Settings >> SSH and GPG keys tab and then on new ssh key and copied the content from id_rsa.pub into the key.</p>
