Trouble connecting Mongoose to MongoDB Atlas cluster: Error EREFUSED

I’m currently working on a MERN stack project and facing an issue while attempting to connect my Mongoose to MongoDB Atlas and i already set IP address to access from anywhere so,i think it’s not IP address whitelisted problem . Here’s a snippet of the code I’m using for the connection:

import { connect, disconnect } from "mongoose";

async function connectToDatabase() {
  try {
    await connect(process.env.MONGO_URL);
  } catch (error) {
    console.log(error);
    throw new Error("Could not connect to MongoDb");
  }
}

async function disconnectFromDatabase() {
  try {
    await disconnect();
  } catch (error) {
    console.log(error);
    throw new Error("could not disconnect from Mongo");
  }
}

export { connectToDatabase, disconnectFromDatabase };

However, I’m encountering the following error:

Error: queryTxt EREFUSED cluster1.wcblrfc.mongodb.net
    at QueryReqWrap.onresolve [as oncomplete] (node:internal/dns/promises:275:17) {
  errno: undefined,
  code: 'EREFUSED',
  syscall: 'queryTxt',
  hostname: 'cluster1.wcblrfc.mongodb.net'
}
Error: Could not connect to MongoDb

What could be causing this ‘EREFUSED’ error, and how can I resolve it to successfully connect to my MongoDB Atlas cluster?

>Solution :

There is connection problem I think.

You can try this code inside the try block:

const uri = `mongodb+srv://${process.env.mongo_user}:${process.env.mongo_password}@${process.env.mongo_DB_cluster}.mongodb.net/${your_DB}`;
await connect(uri);

Instead of this code:

await connect(process.env.MONGO_URL);

I hope it will work.
