SystemWebViewClient: CordovaWebViewClient.onReceivedError: Error code=-6 Description=net::ERR_CONNECTION_REFUSED URL=https://localhost/index.html

Ionic Framework Ionic Angular

Hi,
This project is to be run in production

Current Enviroment → ionic 5.4.16, cordova 10.0.0, android 10, android SDK 30

Current problem ONLY happens in android 10. When using android 9 everything worked perfectly. I have tried to solve this for the past week without success…

What i have tried:

  • Adding <domain-config cleartextTrafficPermitted="true"> to the network_security_config.xml file && adding to the config.xml <application android:networkSecurityConfig="@xml/network_security_config" android:usesCleartextTraffic="true" />

  • Downgrading from WebView 5.0 → 1.2.1

  • Adding to config.xml <allow-navigation href="https://localhost:8080/*" />

  • Adding <allow-navigation href="schema:hostname/*" />
    -Removing WebView completely

All of those attempts returned the same error →

Also tried only using → 

<network-security-config>
    <base-config cleartextTrafficPermitted="true">
</network-security-config>

Using the previous network_security_config.xml, gave me an additional error log after the CordovaWebViewClient error →

E/chromium: [ERROR:tile_manager.cc(793)] WARNING: tile memory limits exceeded, some content may not draw

Any help will be appreciated
