You may receive a "No Connection" Error when logging into your account. Here's some Troubleshooting steps to follow when this occurs.

Step-by-step Troubleshooting Guide:

Check your wifi signal first, if you're iPad shows a connection, make sure that you are able to navigate navigate to a webpage. The easiest way to do this is by opening a browser such as Safari or Google Chrome and navigating to any website. If it loads, it means its connected. If it doesn't load, there's something going on with your iPad's software. Attempt soft resetting the device by turning it off normally with the sleep wake button and turning it back on. If the issue persists, contact Apple support for additional troubleshooting steps.
Next, check that you've updated both the application and the iOS to the most recent version.
If you're all the way updated, check that your network isn't restricting the connection from third party apps, such as TouchCast Studio. For more information on how to bypass a firewall, check out TouchCast Studio: Ports To Get Past A Firewall.
If your ports are ok, finally check that there aren't any VPN profiles on your iPad. A VPN may restrict usage of third party applications such as TouchCast Studio.
