💥 MongoDB Connection Refused Error Fix 💥 Are you seeing the error connect ECONNREFUSED 127.0.0.1:27017 ::1:27017 while trying to connect to MongoDB? This happens when your application cannot connect to the MongoDB server on localhost. The most common reason is that MongoDB is not running. On Windows, you can start MongoDB using the command net start mongodb. On macOS with Homebrew, use brew services start mongodb-community. Make sure your connection string uses IPv4 (mongodb://127.0.0.1:27017) to avoid any IPv6 issues. This simple fix will get your MongoDB server running and your application connected in no time! #MongoDB #ECONNREFUSED #MongoDBFix #NodeJS #BackendDevelopment #127001 #MERNStack #DatabaseError #MongoDBTutorial
