title: Unable to connect to gcloud
body: <p>I am having trouble connecting to a Google Cloud virtual instance. I started up the virtual instance and was able to login as normal using <code>gcloud beta compute ssh</code>.
  I then tried transferring files to the instance using <code>gcloud compute scp --recurse &lt;local_source&gt; \ &lt;user_name&gt;@&lt;instance&gt;:&lt;remote_path&gt;</code></p>
  <p>I got a response of 'Updating project ssh metadata...', which I have never seen before when trying to transfer files. The file transfer failed:</p>
  <pre><code>?\240&lt;username&gt;@&lt;IP&gt;: Permission denied (publickey).
  </code></pre>
  <p>In addition, now I am not even able to log into the VM. When I try to log-in I get:</p>
  <pre><code>ssh: connect to host &lt;IP&gt; port 22: Operation timed out
  ERROR: (gcloud.beta.compute.ssh) [/usr/bin/ssh] exited with return code [255].
  </code></pre>
  <p>As far as I can tell, the firewall rules are still the default and allow connections through port 22. I am still able to log in to the instance through the browser window, but not from the command line. Any help would be greatly appreciated!</p>
