Failed to load "page" resource: Could not connect to the server (iOS app)

In my iOS device App, I’m having the following problem after I let my app a few moment in background and return to it:

This image is from iOS device. I inspected from Safari.

Some screens not work, forcing me to close the app and open again to reload. Why does it happen? How can I solve this?


How was this app installed on your device?
How did you build the app?

The app is already on App Store. I built the app following the steps:

  1. ionic prepare (on terminal)
  2. I opened xcode project in “AppFolder/platforms/ios/App.xcodeproj” and built it there.
  3. And so I followed the steps to publish the app in App Store.

Before this, I already tested in devices directly, through cable in xcode project, and the same this was happening. :frowning:

‘ionic info’ output and ‘package.json’ please.

Any idea what this might be? :frowning:

Are files in your iOS app usually served from localhost:8080?
(Honest question, I actually don’t know)

I executed the app normally. The problem is, when I open the app for the first time, the screens are opened normally, but if I suspend the app pressing the Home Button, and after this open again, the screens which weren’t opened before the suspension give me the error of the images. When I resume the app from background, only the screens which were opened before the suspension can load.

I just solved!!! The problem was because I was using “Cordova WKWebView Engine” as iOS webview, and I don’t know why it was causing me this problem. I uninstalled this webview and now it is working normally. Thanks @Sujan12 :slight_smile:

How did you find out that you were using Cordova WKWebView Engine" as iOS webview?


He probably had this or a similar plugin installed in his project.
