MongoServerSelectionError: connect ECONNREFUSED ::1:27017

I am using Mongo 5.0.1 and Node 17.2.0 this is my code If I connect want to connect with Atlas with this code it runs successfully but when I try to connect with the local Database it gives this error.

const { MongoClient } = require("mongodb");

async function main(){
    const uri = "mongodb://localhost:27017";

    const client = new MongoClient(uri);

    try{
        await client.connect();
        await listDatabases(client);
    } catch (e){
        console.error(e);
    } finally {
        await client.close();
    }
}
main().catch(console.error);

async function listDatabases(client) {
    databasesList = await client.db().admin().listDatabases();

    console.log("Databases:");
    databasesList.databases.forEach(db => console.log(` - ${db.name}`));
};

This is the error I am getting.

Use this as your URI

  const uri = "mongodb://127.0.0.1:27017";

I simply replaced localhost with my IP Address 127.0.0.1 and it works

Syntax: const dbURI = "mongodb://127.0.0.1:27017/MyDB";

in my case, I simply replaced the connection string from 'mongodb://localhost/MyDBName' with 'mongodb://127.0.0.1:27017/MyDBName'. Also, please ensure that the MongoDB server is up and running.

Use this URL:

mongodb://127.0.0.1:27017

Instead of:

mongodb://localhost:27017

I solved this by enabling the IPv6 in the mongodb.config
