Can't connect with remote .Net client

I wrote a simple .Net console client that works fine when running on the ncache server, but when I copy the exe to a different computer and run it, then I get error. Here's the code. Am I doing something wrong? I'm trying to manually connect to the cache server without a config file using the CacheInitParams.

namespace NcacheTest {
    class Program {
        static void Main(string[] args) {
            CacheInitParams config = new CacheInitParams();
            config.BindIP = "x.x.x.x";
            var servers = new List<CacheServerInfo>();
            servers.Add(new CacheServerInfo("x.x.x.x", 9800));
            config.ServerList = servers.ToArray();

            Cache cache = NCache.InitializeCache("mycache", config);

            int counter = 0;
            if(cache.Contains("counter"))
                counter = (int)cache.Get("counter");

            counter++;
            cache.Insert("counter", counter);

            Console.WriteLine(counter);
        }
    }
}

Here's the error:
