ServiiGo HowTo connect

Hi all,

Since I have Serviio Pro, I was unable to connect to it with ServiiGo from my Android phone.
Can someone please inform me what port I am supposed to open ... ?!? ... because port 23424 does not do the trick.

Error message:
Failed to open a connection to the server.
Connect to <domain.com>:23424 timed out.

Please assist,

J.

Ps.
The problem was solved after I forwarded port 23424 from my router to my gateway.
