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?
