Window.close or window.location from oauthcallback.html not working for second time.

I'm using a cordova-salesforce plugin to authenticate users. First time it is working fine. But when i tried to logout, then try to login again (Without closing the application) , then the application redirected to oauthcallback.html defined in www folder and then the following below code will be used to back again to the app's main dashboard.

` window.opener.dstforce({
detail: window.location.href
});
window.close();`
But somehow it will stuck on the splash screen. When i check the console i got an error 'Service not availble'. This was working fine with old versions of ionic-cordova-webview , and also working with cordova- cordova-plugin-wkwebview-engine 1.1.4.
