为什么在 iOS 上运行的空白离子电容器应用程序返回此错误：无法连接到服务器

Question

I'am trying to run a clean blank new Ionic app with capcitor.

I went step-by-step through this tutorial: https://capacitor.ionicframework.com/docs/ios/

Xcode build the app succefully but when the app opens it shows a blank white screen after the splash screen.

In the Xcode logs I see this:

2020-03-13 14:34:44.439927+0200 App[7606:2360127] DiskCookieStorage changing policy from 2 to 0, cookie file: file:///private/var/mobile/Containers/Data/Application/260D9E68-0132-4886-9065-8CC3F016E06C/Library/Cookies/Cookies.binarycookies

SplashScreen.hideSplash: SplashScreen was automatically hidden after default timeout. You should call `SplashScreen.hide()` as soon as your web app is loaded (or increase the timeout). Read more at https://capacitor.ionicframework.com/docs/apis/splash-screen/#hiding-the-splash-screen

System setup:

• Cordova Version: cordova-lib@9.0.1
• Ionic version : 6.2.1
• iOS: 13.3.1
• Mac: Catalina 10.15.3

I'v been creating and deleting apps for the past few days and I'm absolutly lost.

Any help would be good, Thanks in advance.

Lord!

What an embracing bug,

The issue was I ran -host=0.0.0.0 and not --host=0.0.0.0.

For anyone facing this issue I recommend using --external and not --host
