White screen in browser - Java client works



I’ve just installed Metafresh on Ubuntu 16.04.06 via the installer. Went al OK, unfortunate that a newer version of Ubuntu is not yet supported.

When I open url url via a browser (tested with Firefox and Chrome) is only get a white page, noting else. If I use developer tools I see a 503 error. Any idea hot for fix this?

I can open the java client (slow loading), but it works.


Anyone some suggestions?
