Node.js 18.14.x Windows 11 local ubuntu-22.04 on GitHub

Problem description

start-server-and-test fails waiting for http://localhost:3000 locally on Windows 11 with Node.js 18.14.2 and on GitHub in an ubuntu-22.04 runner using the current default Node.js 18.14.1.

Debug logs show

making HTTP(S) head request to  url:http://localhost:3000 ...
  HTTP(S) error for http://localhost:3000 Error: connect ECONNREFUSED ::1:3000

So the IPv6 address ( ::1) is being tested whilst the server is only listening on the IPv4 address (127.0.0.1).

Steps to reproduce

Windows 11 local

Clone https://github.com/MikeMcC399/react-app-test

nvm use 18.14.2
npm ci
export DEBUG=start-server-and-test
npm run test:cypress

test hangs

GitHub

View workflow log https://github.com/MikeMcC399/react-app-test/actions/workflows/test-react-app.yml or fork https://github.com/MikeMcC399/react-app-test and run .github/workflows/test-react-app.yml

Workaround

wait for http://127.0.0.1:3000 instead of http://localhost:3000

On Windows 11

npm run test:cypress:workaround
