title: Github cannot connect using ssh
body: <p>I am setting up my SSH keys with github. Did it numerous times earlier so i am pretty much sure that i am doing it right. But its not working. whenever i clone it just gets stuck there for around 5-10 mins and then returns this</p>
  <pre><code>Cloning into 'sentry-python'...
  Connection to github.com closed by remote host.
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  </code></pre>
  <p>Ran this command to check what's going on <code>ssh -vT git@github.com</code>. One of the many lines in output has this</p>
  <pre><code>Authenticated to github.com ([13.234.176.102]:22) using &quot;publickey&quot;.
  </code></pre>
  <p>Followed official documentation for setting up keys. I believe its something else.</p>
  <p><strong>UPDATE:</strong>
  HTTPs works fine</p>
  <p>Output from: ssh -vT git@github.com</p>
