title: Error when trying to connect to a Cloud SQL instance using the Cloud Shell
body: <p>I've had a Cloud SQL instance for about a year now. </p>
  
  <p>I always accessed it the same way:</p>
  
  <ul>
  <li><p>I would go to my project on the Cloud Console.</p></li>
  <li><p>Click on the Cloud Shell icon at the top right (a small right pointing arrow).</p></li>
  <li><p>A black shell screen would pop up where I would type 
  <code>gcloud sql connect &lt;my instance&gt; --user=root</code>.</p></li>
  <li><p>Enter my password.</p></li>
  </ul>
  
  <p>Now, all of a sudden, I am getting an error message saying: </p>
  
  <blockquote>
    <p>There was no instance found at projects//instances/ or you are not authorized to connect to it.</p>
  </blockquote>
  
  <p>I am the owner of the project, and also have <strong>Admin</strong> rights to the Cloud SQL instance. The project and instance are still there, and my app that accesses the data stored in the instances' database is working fine - therefore I know the database is also present, otherwise my app wouldn't work. </p>
  
  <p>I didn't touch or change anything in the Cloud SQL instance. Suddenly, I simply can't access my database using the exact same procedure I have been using almost every day over the past year now. </p>
  
  <p>I am able to access the database using a local Python script on my laptop and the Cloud SQL Proxy, but I would like to access it from the Cloud Shell again.</p>
  
  <p>Any ideas on what could the problem be?</p>
