Strapi - Axios request on SSR fails with "connect ECONNREFUSED", but CSR works well

System Information
  • Strapi Version: 4.3.0
  • Operating System: Win 64
  • Database: Postgres
  • Node Version: 17
  • NPM Version: 8.1.0
  • Yarn Version: 1.22.19

Request to Strapi during SSR fails for an unknown reason only during SSR. The SSR request hits the Strapi endpoint, I can see the data about to be returned from the controller. I can even see the data if I open the request URL in the browser. But something happens and the request fails.

The request is performed like this:

import { API_URL } from '../config';
import { isJsonString } from '../utils/cookie';
import axios from "axios"

export async function GET(ctx) {
  const { params } = ctx
  const { lang } = params

  try {
    const result = await axios({
      baseURL: API_URL,
      url: '/api/reviews',
      params: {
        locale: lang,
        populate: '*',
        sort: 'createdAt:desc'
    console.log('result :>> ', result);

    return {
      status: 200,
  } catch (err: any) {
    console.log('err :>> ', err);
    return {
      status: 500,
      body: {
          isJsonString(err.response?.data) || typeof err.response?.data === "object"
            ? err.response?.data
            : "DB Error",

What could possibly be a reason for this? I even tried to set header same as in the browser call - same result

Solved, the issue related to Node V17, which has a breaking change related to DNS lookup.

Specifying instead of localhost has solved the issue


Thanks @thousandsofraccoons - this helped me out!

This work for me
Thank you

Can you ask where to fix it, I have the same problem.

window not mac

Thanks! I could not figure this out. I had to add http to the front:

This saved me, thank you very much !
