Scripting - Trigger based server switching

I am trying to implement some basic trigger based server switching based on one of the resources regarding that topic.

My problem is that for some reason it seems to crash the engine when initiated from the trigger, however when initiated manually it works just peachy.

Any help as to why this might be happening is appreciated, I can't seem to figure out the reason.

Here are the code snippets:

Client

function connect(%adr) {
      echo("Connect called with: '" @ %adr @ "'");
      %conn = new GameConnection(ServerConnection);
      %conn.setConnectArgs($pref::Player::Name);
      %conn.setJoinPassword($Client::Password);
      %conn.connect(%adr);
}

function clientCmdConnectServerPortal(%a1)
{
    %adr = detag(%a1);
    echo("Received connect command from server: '" @ %adr @ "'");
    if ( %adr !$= "" ) {
       disconnect();
       connect( %adr );
    } else {
       echo("Error, empty address in ConnectServerPortal");
    }
}

function s1() {
      disconnect();
      connect("IP:192.168.10.8:28000");
}

function s2() {
      disconnect();
      connect("IP:192.168.10.8:29000");
}

Server

datablock TriggerData(ServerPortalTrigger)
{
    tickPeriodMS = 100;
};

function ServerPortalTrigger::onEnterTrigger(%data, %obj, %colObj)
{
    echo ("Entered ServerPortal Trigger: " SPC %obj.getName() );
    %target = detag( %obj.destination );
    %client = %colObj.client;
    if (%client) {
       echo ("Calling client with target = '" @ %target @ "'");
       commandToClient(%client, 'ConnectServerPortal', %target );
    } else {
        echo ("Not a client");
    }
}

function ServerPortalTrigger::onLeaveTrigger(%data, %obj, %colObj)
{
    echo ("Left ServerPortal Trigger");
}

Trigger defined in mission file:

new Trigger(Trigger1) {
      position = "113.743 -281.072 33.7";
      rotation = "0 0 1 37.2422";
      scale = "3 3 3";
      dataBlock = "ServerPortalTrigger";
      polyhedron = "0.0000000 0.0000000 0.0000000 1.0000000 0.0000000 0.0000000 0.0000000 -1.0000000 0.0000000 0.0000000 0.0000000 1.0000000";
         destination = "IP:192.168.10.8:29000";
         locked = "false";
   };

The problem occurs when the switch is initiated by the trigger, switching servers using the two functions s1() and s2() from the console works fine. The trigger based switch crashes the client.

Thanks for any hints regarding this,
