title: ssh-add "Error connecting to agent: Connection refused"
body: <p>My MacBook rebooted and when it does that I have to typically add my private key via ssh-add, using the following command</p>
  <pre><code>$ssh-add ~/.ssh/id_rsa
  </code></pre>
  <p>And I never have any issues,
  Today I am getting this error</p>
  <pre><code>ssh-add ~/.ssh/id_rsa
  Error connecting to agent: Connection refused
  </code></pre>
  <p>What may be causing this? How do I fix it?</p>
