title: Google Cloud Platform SSH error code 1006
body: <p>I made an instance and connected SSH in my project. My project is for machine learning, so I opened jupyter notebook and ran it. But the terminal always sends me an error like this.
  &quot;Connection via Cloud Identity-Aware Proxy Failed
  Code: 1006
  Please ensure you can make a proper https connection to the IAP for TCP hostname:<a href="https://tunnel.cloudproxy.app" rel="nofollow noreferrer">https://tunnel.cloudproxy.app</a>.
  You may be able to connect without using the Cloud Identity-Aware Proxy.&quot;</p>
  <p>I have tried to create firewall rule but this doesn't work.
  Someone says that this is because of session timeout. If it is, what can I do to solve it?</p>
