Introduction

Node.js serves as a powerful platform for building server-side applications, but encountering errors, especially during local development, can disrupt progress. One such error is connect ECONNREFUSED ::1:80, commonly faced while attempting to connect to a local server.

Understanding the Error

The error message connect ECONNREFUSED ::1:80 signifies that the Node.js application is attempting to connect to the IPv6 loopback address (::1) on port 80, commonly used for HTTP traffic. However, the connection is being refused, leading to the error.

const axios = require("axios")try { const { data } = await axios.get('http://localhost')} catch (error) { console.log(error.message) // output: "connect ECONNREFUSED ::1:80"}

Solution 1

You can fix the connect ECONNREFUSED ::1:80 error by explicitly specifying the IPv4 loopback address (127.0.0.1) instead of relying on the IPv6 (::1) address.

const axios = require("axios")try { const { data } = await axios.get('http://127.0.0.1') // Success Response} catch (error) { console.log(error.message)}

Solution 2

Starting from Node.js 17 IPv6 connections are prioritized when making network calls. This is great for future-proofing your code, but it can cause problems if the server you're trying to reach only supports IPv4. This is where setDefaultResultOrder() comes in like a knight in shining armor.

const axios = require("axios")const { setDefaultResultOrder } = require("dns");setDefaultResultOrder("ipv4first");try { const { data } = await axios.get('http://localhost') // Success Response} catch (error) { console.log(error.message)}

Solution 3

Degrading the version of Nodejs runtime to Nodejs 16 or lower can also fix the issue but it is not recommended.
