Mongo Atlas: Connection authentication failed with custom databases : <p>I am trying the Mongo Atlas Cloud. I create a cluster and i am trying a connection with the mongo shell: (same problem with mongo drivers)</p>

<pre><code>mongo mongodb://***-cluster-shard-00-00-***.mongodb.net:27017,***-cluster-shard-00-01-***.mongodb.net:27017,***-cluster-shard-00-02-***.mongodb.net:27017/any_database?replicaSet=****-Cluster-shard-0 --ssl --username ***** --password *****
</code></pre>

<p>this is the connection string in the documentation. And this is the error:</p>

<pre><code>MongoDB shell version: 3.2.7

</code></pre>

<p>I can connect to the database only when i use admin database "/admin?" in the connection string. </p>

<p>THE PROBLEM:</p>

<p>I need to connect to a custom database with the console or mongo drivers.</p>

<p>PD: i protect my data with "***"</p>
