1. Narrow down the scope:

   Data Type	Steps
   On Wi-Fi	Open the desktop from a computer using the same Wi-Fi network. If the issue persists, check your firewall settings to make sure that they are not restricting traffic. Try connecting to a different Wi-Fi network with your mobile app If the issue persists, it's likely an issue with your actual phone.
   On Data	Check with your cell phone carrier for any known issues.
