I'm having trouble connecting Appium to our local Grid.

When I try to connect I don't get any errors, but I do not see Appium in the Grid console.

Here's my node config file.

    {
         "capabilities":
         [
            {
                "browserName":“iPhone5”,
                "version”:”6.1,
                "maxInstances": 1,
                "platform”:”MAC”
            }
        ],
        "configuration":
        {
            "cleanUpCycle":2000,
            "timeout":30000,
            "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
            "url":"http://127.0.0.1:4723/wd/hub",
            "host": “127.0.0.1”,
            "port": 4723,
            "maxSession": 1,
            "register": true,
            “hubPort: 4444,
            “hubHost”: “192.168.28.74”:
    
        }
    }

Has anyone had any success connecting Appium to their own Grid?
