title: Authentication Fail with MongoDB Compass Community
body: <p>I've just created a new MongoDB account and I'm now trying to connect the free cluster I created via MongoDB Compass Community application but I'm getting a 'Authentication Fail' error being displayed.</p>
  
  <p>This is what I've checked so far:</p>
  
  <ol>
  <li><p>From my MongoDB Clusters section when I clicked on the Connect (…) button which then gives you various options. From there, I selected 'Connect with MongoDB Compass' and copied the connection string.</p></li>
  <li><p>This was detected as expected by the Compass and the information was filled automatically in all the relevant fields and I also filled the password by copy/pasting it into the relevant field. 100% sure it is correct.</p></li>
  <li><p>I checked that the username used was indeed set up as an admin and it is.</p></li>
  <li><p>I checked my Authentication database was correct and it is.</p></li>
  <li><p>I've checked that my public IP was added to the whitelist and it is. The only thing I've noticed is that when I added my public IP address, it added a /32 at the end. Is that the port?</p></li>
  </ol>
  
  <p>But I'm not quite sure what else to test for to resolve this problem.</p>
  
  <p>Any suggestions?</p>
  
  <p>Thanks.</p>
