Mongo Error on Deno runtime

Hello I have tried to run a project on deno, but I receive the following error when trying to run it using “deno”

error: Uncaught Error: MongoError: "Connection failed: Connection refused (os error 111)"
        throw new MongoError(`Connection failed: ${e.message || e}`);
              ^
    at MongoClient.connect (client.ts:93:15)
    at async db.ts:5:12

Note:

I have tried it several times but the problem still persists.

Thanks in advance

If you used os is window. Try replace localhost with 127.0.0.1

Thanks for the reply

I have allocated a separate module for database namely db.ts

import { MongoClient } from "https://deno.land/x/mongo@v0.21.2/mod.ts";

const client = new MongoClient();
// await client.connect("mongodb://localhost:27017");
const db = await client.connect("mongodb://localhost:27017/kayran");

export * from "https://deno.land/x/mongo@v0.21.2/mod.ts";

export default db;

Please note that, I did successfully launched my project but after a few re-run deno stopped creating the server and currently it is showing the above error

Thank you
