Home page doesn't show when host is not running #2155
Description
The change made for Proxies in this PR #1938 pushed the home page (our fancy landing page) into the function invoke path. That path has the "host running" filter in place, meaning that if the host is in error the landing page isn't shown, and all you see in the browser is a string like "The host is not running".
The landing page should probably show, even if the host isn't running.
