everything should work out of the box without tweaking config files.
however, i'm not sure we will work correctly if they were tweaked manually.

please try a clean install of your node, then add it from the UI 
(assuming you did a clean rpm install of the engine and didn't tweak any 
of its configuration parameters affecting installation process)
thanks
