[APP][Pro] NetScan (Version 2.0.6, Test Version 2.0.8)

Hi,

I am trying to add my desktop pc, but my firewall is blocking the connection. I tried to open a port, but my there is still no connection. I tried the app Fing to check open ports and there are 0. Really strange because I openen ports in Windows. DO you have any idea what to do?
