title: AWS RDS Network & Security panel not visible
body: <p>I'm new to AWS and I'm having trouble connecting to an Aurora (Postgres compatible) database that I've created.</p>
  <p>I can connect to it via the AWS CLI using the following command:</p>
  <p><code>aws rds-data execute-statement --resource-arn &quot;&lt;my rds cluster ARN&gt;&quot; --database &quot;&lt;My database&gt;&quot; --secret-arn &quot;&lt;My secret in the secret manager&gt;&quot; --sql &quot;select count(*) from information_schema.tables&quot; --profile &lt;my profile&gt;</code></p>
  <p>and this returns a result of 175 which is correct (the same result I get if I run this in the <code>query editor</code> tool in the AWS console.</p>
  <p>I then put together a little C# console app and referenced the <code>Npgsql.EntityFrameworkCore.PostgreSQL</code> nuget package as suggested in the AWS docs. When I run it on my PC I get a connection timeout exception.</p>
  <pre><code>var connectionString = &quot;Server=&lt;My db cluster&gt;; Database=&lt;database name&gt;; User ID=&lt;my user id&gt;; Password=&lt;my password&gt;; Port=5432&quot;;
  
  using (var connection = new NpgsqlConnection(connectionString))
       {
            var sql = &quot;select count(*) from information_schema.tables&quot;;
            return connection.ExecuteScalar(sql).ToString();
       }
  </code></pre>
  <p>When trying to troubleshoot the problem lots of AWS docs &amp; videos suggest setting the <code>Public accessibility</code> property to true by selecting the Db in the RDS console, choosing modify and setting the <code>Public accessibility</code> property.</p>

  <p>The only problem is, when I choose to modify the DB, that panel is not visible. The AWS docs &amp; videos do go on to talk about changing inbound rules and whatnot in VPC and subnets but not before they've changed the <code>Public accessibility</code> property.</p>
  <p>Can anyone advise please?</p>
