Troubleshooting: Green ‘a’ icon but can’t see computer

If the Apptui ‘a’ in your system tray is green (like this: Connected ), but you still can’t see your computer on your phone/tablet, communication ports that Apptui requires might be blocked.

Apptui needs ports 8088, 5353, and 5173 to be open. To make sure they are not being blocked follow these steps:

Windows 7

  1. Go to Start > Control Panel > System & Security > Windows Firewall
  2. While in Windows Firewall in the Control Panel, click Advanced Settings
  3. In Inbound Rules, make sure the Apptui_socketIO, Apptui_tcp, nw and Bonjour Service rules are enabled
  4. Make sure that you don’t have any rules/programs blocking ports 8088, 5353, or 5173

Windows 8 and newer

  1. Press the Windows key and search for “firewall”
  2. Click Windows Firewall
  3. While in Windows Firewall in the Control Panel, click Advanced Settings
  4. In Inbound Rules, make sure the Apptui_socketIO, Apptui_tcp, nw and Bonjour Service rules are enabled
  5. Make sure that you don’t have any rules/programs blocking ports 8088, 5353, or 5173
