title: Google Cloud Storage HttpAccessTokenRefreshError: invalid_grant: Bad Request
body: <p>I am receiving this error <code>oauth2client.client.HttpAccessTokenRefreshError: invalid_grant: Bad Request</code> when I try to connect to a Google Cloud Storage bucket in any of my projects (all of which were working previously).</p>
  <pre><code>from gcloud import storage
  client = storage.Client() 
  bucket = client.get_bucket(bucket_name)
  </code></pre>
  <p>I signed into my gcloud account through command line on a co-worker's laptop and the script connected to Cloud Storage fine. My co-worker then signed into his gcloud account on my computer and it did not work for him either. We assumed it was the server time issue that many other posts reference or something very wrong with my computer.</p>
  <p>We ran <code>ntpdate</code> and got <code>8 Nov 12:00:38 ntpdate[3468]: no servers can be used, exiting</code> we also went through using <code>ntpd</code> but to no avail.</p>
