Mac M1

Wait-on does not seem to work with mac m1, see package.json relevant parts below.

The app will load in the browser but the electron app will never appear. Work fine on the previous macbook and works fine if I change electron:start to , "electron:start": "concurrently -k "cross-env BROWSER=none yarn start" "electronmon ."", where the app then loads blank and I refresh manually.

"start": "react-scripts start",
"build": "react-scripts build",

"eject": "react-scripts eject",
"electron:start": "concurrently -k "cross-env BROWSER=none yarn start" "wait-on http://localhost:3000 && electronmon ."",

I also tried with 127.0.0.1:3000 instead, same issue.

I have a mid 2015 mac and came here with the same issue. I did a massive brew update yesterday which also bumped node and yarn. Maybe it's not related to M1 actually?

Same issue, doesn't work at all. M1 mac.

Temporary workaround for this I found was to add waitFor into the electron script e.g.
Add the below to your createWindow method.

async function createWindow() {

  // wait for localhost:3000 to
  // become available.
  if (isDev) {
    const waitOn = require('wait-on');
    await waitOn({
      resources: [
        'http://localhost:3000'
      ],
      validateStatus: function (status) {
        return status >= 200 && status < 300; // default if not provided
      }
    });
  }

We're running into this in a Jest test scenario too - on an M1 await waitOn({resources: ['tcp:localhost:3000']}); is not returning, while it works on other machines (and that port is in use).

Change it to tcp:127.0.0.1:3000. By default, the DNS resolver of the machine will return IPv6 first. If the service is not aware and listening to both IPv, it will fall into a timeout
