MongoDB doesn't connect. [MongooseServerSelectionError: connect ECONNREFUSED ::1:27017]

Note: I have already gone through the following similar threads and tried the following options:

  1. Restarted the MongoDB service.
  2. Replaced localhost by 0.0.0.0.
  3. Replaced local host by 127.0.0.1:27017

timeoutError - MongoServerSelectionError: connect ECONNREFUSED ::1:27017 - [NodeJS + MongoDB]

MongoNetworkError: failed to connect to server [localhost:27017] on first connect [MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017]

MongooseServerSelectionError: connect ECONNREFUSED ::1:27017

MongooseServerSelectionError: connect ECONNREFUSED ::1:27017 error

Following is the code from index.js file:

const mongoose = require("mongoose");
mongoose.connect("mongodb://localhost/db_c");

Nodjs version: v18.13.0

MongoDB version: 6.0.5

Mongoose version: 7.2.2

The error I am getting is:

E:\nodejs\app1\node_modules\mongoose\lib\connection.js:792
    err = new ServerSelectionError();
          ^

I am an absolute beginner and seek your help.

I also had the similar connection problem with node 18.16.0. I downgraded it to 16.13.0, and it worked fine.

Edit: I got it to work with node 18.16.0. There is a breaking change starting node 17 that it uses IPv6 instead of IPv4 as default. I had to modify my mongod.conf for that. The instructions are quite simple (https://www.mongodb.com/docs/manual/reference/configuration-options/#net-options). I am using node driver not mongoose. There are issues with compatibility with version of DB that I also had to work out.
