Error

error: Uncaught Error: No such host is known. (os error 11001)
    at unwrapResponse (rt\10_dispatch_json.js:24:13)

    at async Object.connect (rt\30_net.js:221:13)
    at async MongoClient.connect (client.ts:41:14)
    at async mongodb.ts:33:1

Mongodb.ts File

import { MongoClient } from "https://deno.land/x/mongo@v0.21.0/mod.ts";
    
    const client1 = new MongoClient();
    await client1.connect("mongodb+srv://user1:MYPASSWORD@cluster0.hmdnu.mongodb.net/TestingDB?retryWrites=true&w=majority");
    
    const db = client1.database("TestingDB");
    
    export default db;

I used this command to run my server

deno run --allow-net --allow-write --allow-read  --allow-plugin --unstable server.ts
