Unable to add object to speed cache

I just installed Velocity on my computer and everything is working fine, except that I cannot add any objects to the cache.I have no problem fetching the cache itself, but when I try to add an object everything just hangs at for five minutes and then I get a timeout.

My code for connecting to the cache host (works great):

// Define Array for 1 cache host.
ServerEndPoint[] servers = new ServerEndPoint[1];

// Specify Cache Host Details 
servers[0] = new ServerEndPoint(
       "COMPUTERNAME" /* Host  */, 
       22233 /* Port */, 
       "DistributedCacheService" /* Service name */);

// Pass configuration settings to CacheFactory constructor.
m_cacheFactory = new CacheFactory(servers, 
       true /* Use routing client */, 
       false /* No local cache */);

// Get the cache (works fine).
Cache cache = m_cacheFactory.GetCache("MyCache");

      

        
        
        
      

    

My code for adding object to cache (doesn't work):

// Get the cache.
Cache cache = m_cacheFactory.GetCache("MyCache");

// Create the item to put in the cache.
Product product = new Product();
product.Sku = "10000";
product.Name = "My Product";

// Put the object in the cache (The add method doesn't work either).
cache.Put(product.Sku /* Key */, product /* Value */);

      

        
        
        
      

    

Through the cluster admin interface, I verified that the host cache is running and that the cache itself exists.

Can anyone understand what the problem is?

EDIT:

I connected the log provider to the factory cache and I checked that there is some kind of timeout. The cache host is on my local machine and the firewall is disabled.
