I’m currently trying to browse localhost url using th inappbrowser but this is the error I get:
Cannot GET /192.168.4.1 and this is my ts and html:

<ion-content padding>
      <button ion-button (click)="openWithInAppBrowser('192.168.4.1')">Open with In App browser</button>
  </ion-content>

public openWithInAppBrowser(url : string){
    let target = "_blank";
    this.theInAppBrowser.create(url,target,this.options);
}

How can I browse the localhost url?
