iOS 11, Xcode 9 Error: NSURLConnection finished with error-code-1100 (1)

NSURLErrorFileDoesNotExist = -1100

What file are you trying to load? index.html or something else?

Sometimes there is a timeout error if it is the index.html.

I'm getting this error when working in JS and Ionic 3. I'm testing on my iPhone 7 plus with iOS 11 and Xcode 9.

NSURLConnection finished with error - code -1100

Anyone got a similar error in the past?
