Can't install Flowable BPMN designer on Eclipse

I can’t install Flowable BPMN 2.0 designer as plugin to Eclipse 4.6.3 by accessing http://www.flowable.org/designer/update/. In fact the url is not accessible at all from the browser using http or https links.
Who I need to contact to resolve this issue?
