title: why is my github copilot not working all of a sudden?
body: <p>I have been using copilot for a while now, and one fine day on opening VSCode this error appeared.</p>
  <p>&quot;[ERROR] [default] [2022-04-09T08:38:10.995Z] GitHub Copilot could not connect to server. Extension activation failed: &quot;certificate has expired&quot;</p>
  <p>I looked up for it everywhere and found nothing, it'd be a great help if someone could fix this for me!</p>
  <p>[here's the error and how the extension looks like on the status bar]</p>
