Socket connection timeout

Working with Data Node.js Frameworks

I have a mongodb database that I am connecting to with mongoose in nodejs. When I try connect to the serverless instance, it will normally work. However, I keep getting Socket connection timeout. If I manage to connect, once I refresh/restart the server, I get the socket error again. I am struggling to traceback the error to see what is causing it… Can anyone help?

I have also tried to connect using the mongodb nodejs package instead to see if it was an error with mongoose. Unfortunately, I get the same error still.

db.js:

const { MongoClient, ServerApiVersion } = require('mongodb');

module.exports = async () => {

	// Create a MongoClient with a MongoClientOptions object to set the Stable API version
	const client = new MongoClient(process.env.SERVERLESS_DB_URI, {
	  serverApi: {
	    version: ServerApiVersion.v1,
	    strict: true,
	    deprecationErrors: true,
	  }
	});

	try {
		// Connect the client to the server	(optional starting in v4.7)
		await client.connect();
		// Send a ping to confirm a successful connection
		await client.db("admin").command({ ping: 1 });
		console.log("Pinged your deployment. You successfully connected to MongoDB!");
	} finally {
		// Ensures that the client will close when you finish/error
		await client.close();
	}
};

Error:
