Failed connection UDP Server C# . Socket exception 10060

Question

I´m trying to make a UDP server in c# ussing Microsoft Visual Studio. Few days ago, I connected properly the client and the server, and I have been able to read and process the received data. However, I modify to add a new socket couple to the UDP server. And from this moment until now never works again. Always I receive the same exception (10060).

I know that I have some lines without use, and also I know that I´m not ussing the socket of the 3 Slave.

Always I have the same excepttion. I´m not connecting to the remote host.

With Wireshark I have checked that I´m receiving some packets with the proper message. The client is in one Pc and the server in other.

Ty in advance.

I tryed to receive mesages from a client. I have the clients in one Pc and the server in other. Always I´m receiving the same exception (10060). I can´t connect weith the clients.
