Browser does not take a url with parameters

I am using the following method to embed a webpage in a matlab figure. But the parameters in the url (num=20&site=x) do not get passed to the website. This happens only to some computers. I am not sure if it's matlab version, or some components in Matlab. Anybody know a reason and how to fix it?

      jObject = com.mathworks.mlwidgets.html.HTMLBrowserPanel;
          [browser,container] = javacomponent(jObject, [], f);    
          set(container, 'Units','norm', 'Pos',[0.55,0.05,0.44,0.45]);
          browser.setCurrentLocation('https://www.mysite.com/index.php?num=20&site=x');
