CUDLR crashing on start, some iOS devices

[tenpn]

Check out the SocketException below. This happens to one of our (remote) testers when they boot the game either on an iPad 1 (iOS 5.0.1) or iPod 4th Gen (iOS 6.1.3). On my 4S (iOS 7.0.3) I found I got the same crash if I was on 3G instead of wifi.

Thanks, I'll add some additional error handling to the startup. It looks like those machines can't resolve the hostname you're using.

Aw fuck, ServerInfo.Awake() is actually my code - I'm trying to fetch the IP to display it on screen, to make connecting to CUDLR easier for QA. Here's what I'm doing:

var host = Dns.GetHostEntry(Dns.GetHostName());
foreach (IPAddress ip in host.AddressList)
{
    if (ip.AddressFamily == AddressFamily.InterNetwork)
    {
        m_ipAddress = ip.ToString();
        break;
    }
}

This isn't cudlr's fault, so feel free to close this. But if you know a better way to fetch this info, maybe direct from CUDLR, let me know.

Ah, that's a nice feature. Maybe try: var ipaddress = Network.player.ipAddress;
