body: <p>I've been trying for over 2 hours now trying to figure out what's wrong with this database. I've tried everything. From reinstalling the server, restarting the processes, rebooting and so much more. It keeps giving me this error when trying to connect:</p>
  <pre><code>const serverSelectionError = new ServerSelectionError();

  <p>This error wont resolve no matter what I do. The MongoDB server is running, I've checked by doing &gt;show dbs and it lists them perfectly fine. Also, C:/data/db exists and its fine too.
  What do I do?
  Here's my connection code:</p>
  <pre><code>(async () =&gt; {
      await require('./other/DB/mong')();
      console.log(&quot;Connected to Database.&quot;);
  })();
  </code></pre>
  <p>and here's ./other/DB/mong:</p>
  <pre><code>var mongoose = require(&quot;mongoose&quot;);
  
  module.exports = async () =&gt; {
      await mongoose.connect('mongodb://localhost:27017/MX', {
          keepAlive: true,
          useNewUrlParser: true,
          useUnifiedTopology: true
      });
      return mongoose;
  }
  </code></pre>
