Domoticz

I would like to connect the pilot app with my domoticz. I forwarded the port to the pi and checked this here:

http://www.yougetsignal.com/tools/open-ports/

There it says, that the port is open. But when I try to connect the app, I always get the message, that it couldn't connect to the server. Could anyone explain me, how to connect the app with domoticz?

Do you get entries in the domoticz log? The port forward is pointing to the correct internal ip?

I already solved the problem without Pilot App, but with my.domoticz.

But thanks a lot for your help
