URLs not working with TCPObject

Hi! I have been out of the scripting game for some time; however, I don't think my memory is this bad.

Problem: When connecting to a chat server from a chat client using a TCPObject, the server accepts the connection, but then disconnects when passing a URL instead of an IP (e.g. "localhost:20010"). When passing an IP it works fine (e.g. "192.168.10.101:20010").

Here is the way I declare my TCPObject object and open a connection:

function chatConnect(%server,%port,%nick)
{
  
   // build address string (server:port)
   %address = $Pref::Server::URL @ ":" @ $Pref::Server::Port;

   echo("address is " @ %address);

   // create a new TCPObject for our network code
   new TCPObject(chatConnection);
	
   // attempt to connect to the server
   chatConnection.connect(%address);
}

This is the server side code accepting the connection and storing the client:

function chatConnection::onConnectRequest(%this,%address, %id)
{	
   // create a new TCPObject, and pass the new socket ID in as an argument
   %client = new TCPObject(chatClient,%id);

   // Record our new client
   // Notice that we save the new TCPObject in the clientID slot.  This allows us to not
   // only cross reference later, but to use it to send and receive for that client.
   // We can actually make calls off it.  $clients[%i,"clientID"].function() is a valid call.
   %i = findOpenClientSlot();
   $clients[%i,"clientID"]       = %client;
   $clients[%i,"clientNickname"] = "guest";
   $clients[%i,"connected"]      = true;
   $clients[%i,"ActiveRoom"]     = "public";
}

When I use an IP address everything works fine and I can interact with my server. However, if I specify a URL instead, the console shows the server recognizing that there is a connection request, but it does not connect. It goes through the onConnectionRequest, and then goes straight to the onDisconnect() method.

Nothing is different between the two connection attempts aside from using a URL instead of an IP.

Any help is greatly appreciated.
