Ionic 4 inappbrowser https proxy issue

I’m basically using Ionic 4 to build an IOS Application. I use the InAppBrowser to open a remote URL ( Private network only, uses proxy) to enter credentials, And I capture the token which is generated in a different URL. Redirection fails due to HTTPS Proxy.

The error received is,
WebFilterIsActive returning: NO
