Hello, my friend can’t come on my private serveur, he don’t view it thanks for your help.
You need to add the port you are using (default is 30120) to your modem/router’s firewall to allow outside users to connect to your IP using that port. It clearly says this on the download page for setting up a server.
Port forward the port 30120 (UDP & TCP)
example when connecting as a different user would be xxx.xxx.x.xxx::30120
