react-native: Image from url loads with https but fails loading with http

I am trying to display a simple image from an URL in the iOS Simulator. When the URL is a https domain it works fine but when I try loading from a http domain the image is not loaded. Via the inspector you can see that a blank image was created. My code is the following: render() { return ( <View> <Image source={{uri: 'https://facebook.github.io/react/img/logo_og.png'}} // source={{uri: 'http://facebook.github.io/react/img/logo_og.png'}} style={{width: 400, height: 400}} onLoadStart={() => console.warn('loading started')} onLoad={() => console.warn('loading successful')} onLoadEnd={() => console.warn("loading endet (successful or not")} /> </View> ); }

I already tried:

• Restarting the packager and the iOS simulator (no change)
• Reset Contents and Settings of the iOS simulator (no change)
• Tried several other images via http and https
• Created new project from scratch via react-native init myurltestproject` and added code from above (still not working for http images)

I am using:

• react-native-cli: 1.0.0
• react-native: 0.28.0
• macOS 10.10.5 (Yosemite)
• MacBook Pro 13inch early 2015

Side note: Interestingly when I try to run the exact same code on the simulator but via Deco IDE (Version 1.1.2 (0.7.0)) http and https url are working.
