React Native SocketProtocol Error and TimeoutError

I can't seem to figure this out at all. When ever I open my React Native application I get these errors. The best I have found is that it's something to do with how the applications is being bundled. Any help would be much appreciated and upvoted! Thanks!

Errors from xCode
