1) Is your iPad on the same network as your Raspberry Pi? In otherwords, are you connecting through the cell network on your iPad and are on a local network (like a wireless network) with your Pi?
2) If you are trying to connect from outside your network have you poked a hole in your router/firewall to allow the connection?
2) If you are on the same network, have you tried the testing procedure in the documentation?
The procedure essentially is:
Testing the RasPiConnectServer To test that your RasPiConnectServer is running correctly, do one of the following: On your Raspberry Pi, type into a web browser: port number>/Version
example: OR On another computer (on the same local network), type into a web browser IP Address>:<Your port number>/Version
example: 192.168.1.130:9600/Version To find out your local IP number type: ifconfig If you see "RasPiConnectServer Version X.Y", then you are successfully running the RasPiConnectServer Testing the RasPiConnect App 1) Make sure you are running the RasPiConnectServer and it passes the above test 2) Go to the Settings Tab on the RasPiConnect App and make sure that the Username and Password match the Username and Password in the RasPiConnectServer 3) Add a System URL pointing to your Raspberry Pi (including port number), making sure you append the "raspi" to the end ( example: raspberry.example.com:9600/raspi ) 4) Go to the Settings Tab -> Server Report The line corresponding to your Raspberry Pi should have a green LED indicating a connection was successful 5) On the initial Demo page, go to the Panel Setup Tab and change the "Server Status" control to point to your added System URL 6) Hit Refresh on the Control Panel Tab and your indicator should change to Green.
