If you have seen this error, then what does it mean? GET http://localhost:3000/ net::ERR_CONNECTION_REFUSED For me, It simply means: ✅ your browser tried to connect to localhost:3000 ❌ but nothing is running on that port, so the connection gets refused. Most common causes: - Server isn’t started - Wrong port - Backend crashed - Docker port not exposed correctly (if you use Docker) Debugging tip: always check what’s listening on the port before wasting hours.
