ok so i have a problem where like that its working(on ipv4 address and local address):

C#

IPAddress ipaLocal = ipAddress;
tlsClient = new TcpListener(1986);

and like that its not working on ipv4 address:

C#

int port = 1986;
IPAddress ipaLocal = ipAddress;
tlsClient = new TcpListener(ipaLocal,port);

its because its not suppose to work with ipv4 address and with only local address?
and another thing is that i made is that you can close your server and relisten to clients without close the app but there is an error where its says: "only usage of each socket address is allowed", i checked in all the code and found nothing that have been left open.
thank for your time and help!!
the code:[C#] chat server - Pastebin.com[^]
its based on a chat that i found on the internet.

Solution 1

only local address:

C#

var tcpListener = new TcpListener(IPAddress.Parse("127.0.0.1"), 1986);
tcpListener.Start();

or working on any IPv4 address:

C#

var tcpListener = new TcpListener(IPAddress.Any, 1986);
tcpListener.Start();
