Switch Ros Web Server Protocol

edit

I'm trying to load a Ros Web Server into an app for android/IOS using NativeScript, however, the web page generated uses http protocol as opposed https, and as such yields this error when you try to embed it. I'm not too familiar with web programming within C++, so I wanted to know if there would be a method to alter the source code of the ros_web_server code to generate a https site rather than http. Thanks.
