Which ports to open in firewall?

The server app contains port 23424 and 23524 , not specifying protocol.
Also: in the mean time, I connected the Android client to local IP, it does show how many arttsts there are , and the albums, and the cover, number of items inside...but when entering everything is "No content"
However: the Android client does not fail to already annoy me with ads, is that gone when paying for "pro" version of the server?

For the firewall ports, I believe TCP is the only protocol necessary. But to be honest I have mine set for TCP/UDP.

I haven't used the ServiiGo app in years (don't have an Android device) so I can't offer any suggestions with that one.
