Ports for desktop app

[PeterFouq]

Hi,

I'm using a restricted network in my flat wich is provided by the residence hall.

I know there are already a few existing topics related to my request, but all of them are quite old, there is no official note about it, and I would like to be sure I request them to open the good ports once and for all.

What are the ports I actually need them to open to poperly use the desktop app ?

Thanks a lot !

Best regards
