I haven't seen that error, but I have been taking a look at using WebServices over proxy. You can modify your application config, to use the proxy server if that is the problem you are having. If it is as runtime, you can add some this to you application config.

<configuration>
   <system.net>
      <defaultProxy>
         <proxy 
	    usesystemdefault = "false"
            proxyaddress = "http://YourProxyServer:Port8080"
            bypassonlocal = "true"
	  />
      </defaultProxy>
   </system.net>
</configuration>

I didn't exactly understand your question, but i hope that helps.
