Check and make sure the Windows PC and the mobile device connected to the same Wi-Fi router. To verify this, on the mobile device, open the Web browser and type http://Server_IP:80/AEM/. If AEM is launched successfully, it means that the PowerServer is properly installed and that the mobile device is able to connect to the Windows PC.
NOTE: Mobile Internet is supported by PowerServer Mobile. However, in order for the Appeon Workspace to connect to your PowerServer you will need an external IP address. You can verify that your external IP address is properly working by typing http://External_IP_Address:80 into a Web browser of any device connected to the Internet. If you get a page not found error or other HTTP error then your network is not configured properly for external access.
