Ionic 1 App WhiteScreen

I’m facing a problem when trying to serve or build my ionic 1 app.
On serve I get no error messages, however only a white screen appears.
When I build I get the following message:

Could not successfully update network info during initialization.

However on simulator my loading page appears and after that I get the white screen again.

I have tried changing the following SplashScreen preference

<preference name="AutoHideSplashScreen" value="false" />
<preference name="SplashScreenDelay" value="10000" />
<preference name="FadeSplashScreen" value="false" />
<preference name="FadeSplashScreenDuration" value="1" />
<preference name="ShowSplashScreenSpinner" value="false" />

I also tried in Xcode [SOLVED] NSURLConnection/CFURLConnection HTTP load failed

I have checked the following in my code and everything is as it’s supposed to be.

Any ideas on how to solve this ?
Thanks in advance
