JavaFX Webview on a Swing application not loading content which loads properly on standard web browsers

Question

I have a Java/Swing application through which I want to load and display web pages from this URL : http://funsoft.systempartners.biz:8042/stone-webviewer/index.html?study=2.16.840.1.113669.632.20.1211.1000035777

This URL has testing content only. The JavaFX Webview component tries to load it indefinitely while it loads instantly on standard web browsers.

Many versions of JavaFX have been tested but with similar results, the latest one being 16.

I have attached the code that I am using below. Any suggestions on why the content cannot be processed successfully? Much appreciation in advance.

Thanks,

Charles
