Unable to launch tests with RemoteWebdriver agaisnt the emulator

[Nicolae]

Hello,

I'm trying to launch my tests remotely against a android emulator (they work locally against the same emulator) but it seems it can not connect
my Driver:
        driver = new RemoteWebDriver(
              new URL("http://10.34.21.30:4444/wd/hub"),
              DesiredCapabilities.android());

error:

System info: os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.6.0_21'
