!Hello, good afternoon!

Did someone knows how to work with ephemeral ports and Ignition?  
I have a server and is connected to my pc with a network cable, then I am using these ports but sometimes Ignition got disconnect for the ports.

Ignition doesn't choose ephemeral ports. Your client OS does so when initiating a TCP connection, and the OS running Ignition responds to them on Ignition's behalf. You will need to study your OS's settings, including firewall settings.
