I suspect this is only a problem during development.
I am working directly from the 4.1.2 release and not original source code. I am changing some of the configuration parameters so I can use a FQDN for the hosts rather than localhost.
When I browse to the XDSToolkit, it works fine. When I browse to the FHIR Toolkit, I get an empty page.
I opened a different browser that had not seen the URLs previously, and things worked as expected.
I suspect a browser cache issue. Not sure there is anything you can do to make this better. It might be worth a note in the Installation and/or Configuration notes that if you run initially using localhost and then change to an FQDN later or possibly change the ports, you might want to flush the browser cache.
