Ionic 3 Livereload not working on Android device

Ionic Framework ionic-v3
1

In one of my projects where the --livereload flag was working , suddenly the feature is not working but I see Launch Success message on my console.

After launching the app on my android device the Splash screen stays on infinitely and then a message appears as

Application Error
net::ERR_CONNECTION_TIMED_OUT 
(http://192.168 .0.102:8100/)

My config XML has the following :

    <preference name="loadUrlTimeoutValue" value="700000" />
    <preference name="SplashMaintainAspectRatio" value="true" />
    <preference name="SplashScreen" value="screen" />
    <preference name="AutoHideSplashScreen" value="false" />
    <preference name="FadeSplashScreen" value="false" />
    <preference name="SplashScreenDelay" value="300000" />
    <preference name="SplashShowOnlyFirstTime" value="false" />
    <preference name="ShowSplashScreenSpinner" value="true" />

So it specifically mentions loadUrlTimeoutValue as 700000 - but that did not have a positive effect !

Then I added an Inbound Rule to my Windows Firewall to allow specifically the following ports : 8100, 35729, 53703 as these appeared on the console with the following command:

ionic cordova run android --livereload --consolelogs

> ionic-app-scripts serve --address 0.0.0.0 --port 8100 --livereload-port 35729 
--dev-logger-port 53703 --consolelogs --nobrowser --iscordovaserve 
--platform android --target cordova

This also did not help …

Finally I added the following permissions to AndroidManifest.xml -

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

that too did not solve the issue.

My Ionic Info is as follows:

I am stuck with the above problem - I will highly appreciate if any fellow devs could get me out of this soup!!

Thanks in advance.
