title: Not able to connect on Mongodb Atlas port
body: <p>I'm using an M0 GCP instance.</p>
  
  <p>I can connect to the cluster using this string:</p>
  
  <pre><code>'mongodb+srv://my_user:my_pass@my_cluster-mbsnz.gcp.mongodb.net/db?retryWrites=true&amp;w=majority'
  </code></pre>
  
  <p>I'm trying to use another client where I need to pass host and port, but I can't connect.</p>
  
  <p>I tried telnet to the port 27017, but for some reason I'm not able to connect directly on the port.</p>
  
  <pre><code>curl http://my_cluster-mbsnz.gcp.mongodb.net:27017
  curl: (7) Failed to connect to my_cluster-mbsnz.gcp.mongodb.net port 27017: Connection timed out
  </code></pre>
  
  <p>or </p>
  
  <pre><code>telnet my_cluster-mbsnz.gcp.mongodb.net 27017
  Trying 185.82.212.199...
  ^C -&gt; After a long time waiting
  </code></pre>
  
  <p>What might be wrong ?</p>
