Failed to load webpage with error: Count not connect to the server

Dear All ,

Could you please help us diagnose the following issue?

The issue is reproduced according to the below steps:

The precondition: APP is upgraded to cordova-plugin-ionic-webview

The reproduced steps/scenarios are as below:

1.Open the app.

2.Press Home key.

3.Go to the backend process, to ensure the IOS is hung up in the backend.

4.Keep the app open for 2 Days in the backend and never open the app screen to do anything again.

5.After 2 days, we will recieve one app message push.

6.Right now open the App, we found that the process might be killed as cordova will restart the process to reload the webview.

7.we found that the app will be failed to open and it will stay at the splashscreen.

8.We checked the log is that " Failed to load webpage with error: Count not connect to the server."

Due to the above issue, we can't directly open the APP continually, and we just find only way to open the App again that we close the process in the backend.

We are not sure if the current port 8080 is occupied, so the server will not be started up.

We tried many methods to fix it, but the issue is still plagued us so far, and we don't know how to fix it.

Could you please help us on this? Thanks.
