Mongoose ECONNREFUSED Error (querySrv)

Many developers recently face this error while connecting to MongoDB Atlas using mongodb+srv://: querySrv ECONNREFUSED _mongodb._tcp.<your-cluster>.mongodb.net 🔍 What this means This error occurs when Node.js fails to resolve DNS SRV records, which are required for mongodb+srv:// connections. Even if: ✅ MongoDB Atlas is configured correctly ✅ IP is whitelisted ✅ Credentials are correct 👉 The connection still fails due to DNS resolution issues. ✅ Solution (Working Fix) Add the following at the very top of your server.js or index.js: import dns from "dns"; // Force reliable DNS servers dns.setServers(["8.8.8.8", "1.1.1.1"]); OR import dns from "node:dns/promises"; dns.setServers(["1.1.1.1", "1.0.0.1"]);
