it should still fix some issue Your code is correct. The problem is with the networking.
In your current code, you are trying to send UDP packets to several clients at their corresponding IP addresses and a port (3790).
code :
External IP:port    <-------------->    Local IP:port

   w.x.y.z:55000    <-------------->

I wish this helpful for you When you fork a process, you get a whole new copy if its data. Specifically, each server process has its own copy of connectedClients, which has the value of the parent process at the moment of the fork. If the server parent process later updates connectedClients, the then-existing server child processes will never know.
Try printing the value of connectedClients from your child server processes to see what I mean.

Hope that helps You can take a loot at groups
When an user join the game, you just add it to a group:
code :
public Task JoinRoom(string roomName)
    return Groups.Add(Context.ConnectionId, roomName);
public Task LeaveRoom(string roomName)
    return Groups.Remove(Context.ConnectionId, roomName);

This might help you As per John Bollinger's very helpful last comment: "(...) the server can relay messages only via its responses to RPC calls by clients. (...)"
So basically no, clients cannot communicate directly with other clients. They can send and ask for information through a call to the server, and it is through those requests that it is possible to "communicate" from one client to the other.
