Application won't connect to Reactotron (iOS Simulator)

[FR073N]

When running my application in the iOS Mac Simulator, it won't connect to Reactotron even if I should have the good configuration.

My configuration used to work before, but after some changes it doesn't anymore. I checked with the demo app and it's correctly connecting.

Here are my app configs :

reactotron.js :

/* eslint-disable no-console */
/* global __DEV__ */

import Reactotron from 'reactotron-react-native';
import AsyncStorage from '@react-native-community/async-storage';
import { reactotronRedux } from 'reactotron-redux';
import sagaPlugin from 'reactotron-redux-saga';

const reactotron = Reactotron.setAsyncStorageHandler(AsyncStorage);

// connecting the app
reactotron.configure();

// plugins
reactotron.useReactNative({
  storybook: true,
});
reactotron.use(
  reactotronRedux({
    isActionImportant: action => action.type.startsWith('core/'),
  }),
);
reactotron.use(sagaPlugin());

if (__DEV__) {
  Reactotron.connect();
  Reactotron.clear();
}

if (__DEV__) {
  console.tron = Reactotron.logImportant;
} else {
  console.tron = console.error;
}

export default reactotron;

I checked with reactotron react-native demo app to compare if it's a port / hostname error, and I have exactly the same outputs when checking my ports :

Try adding host in configure method. Here localhost work well, but sometimes I need putting my Mac's IP address

reactotron.configure({ host: 'localhost' });

or

const host = <IP_ADDRESS>
reactotron.configure({ host });
