Problems with connecting my function to mongoDB

I’m trying to connect my function with my mongodb database (also on digitalocean) but I can’t. I already tried it with Mongoose and MongoDB, here are the codes:

Mongoose:

  try {
    // await mongoose.connect('mongodb+srv://my-digital-ocean-url');

    mongoose.connect('mongodb+srv://my-digital-ocean-url', (err) => {
      if (err) throw new Error(err);
      console.log(`MongoDB Connection: ${mongoose.connection.readyState}`);
    });

    // console.log(`MongoDB Connection: ${mongoose.connection.readyState}`);

    return {
      body: { 'MongoDB Connection': mongoose.connection.readyState },
    };
  } catch (error) {
    return {
      body: { Connected: false },
    };
  }

I’ve tried both methods: using await, the function returns a timeout error, even if I set the timeout to 30 seconds in project.yml; using .then in the parameters, I always get a “connecting” status.

  const client = new MongoClient('mongodb+srv://my-digitalocean-url');

  try {
    await client.connect();

    // console.log(`Connected`);

    return { connected: true };
  } catch (e) {
    console.error(e);
    return {
      body: { connected: false },
      statusCode: 400,
    };
  } finally {
    await client.close();
  }

Using mongodb, i always get a timeout error.

But the weird thing is: the exact same code works using the node command on my machine (that’s what the console.log is for). I literally used ctrl+c ctrl+v on this, what did I do wrong?
